The great cubicuboctahedron is a convex Archimedean solid that consists of 48 isosceles triangles, 24 squares, and 8 hexagons. It can be classified by its vertices, edges, and faces: it has 48 vertices, 72 edges, and 80 faces. This shape is notable for its unique combination of geometric elements, combining aspects of both a cubic shape and an octahedral shape, reflected in its complex symmetry and structure.
The Great Ditrigonal Dodecicosidodecahedron is a complex polyhedron and is one of the Archimedean solids. It can be described in terms of its geometry and characteristics: 1. **Vertices, Edges, and Faces**: It has 120 vertices, 720 edges, and 600 faces. The faces consist of various types of polygons, including triangles, squares, and hexagons.
The great icosacronic hexecontahedron is a complex polyhedral shape belonging to the category of convex polyhedra. Specifically, it is one of the Archimedean solids, characterized by its unique arrangement of faces, vertices, and edges. To break down the name: - "Great" suggests that it is a larger or more complex version compared to a related shape. - "Icosa" refers to the icosahedron, which has 20 faces.
The Pentakis snub dodecahedron is a type of convex polyhedron and a member of the Archimedean solids. It can be described in a few ways: 1. **Description**: The Pentakis snub dodecahedron is derived from the regular dodecahedron by adding a pyramidal "cap" on each of its pentagonal faces.
The nonconvex great rhombicuboctahedron is a type of polyhedron that belongs to the category of Archimedean solids. It is classified as a nonconvex solid due to its shape, which includes inwardly drawn faces. ### Characteristics: 1. **Base Shape**: The nonconvex great rhombicuboctahedron has a structure that combines elements of various shapes, specifically squares and triangles.
A hexagonal trapezohedron is a type of geometric shape, specifically a polyhedron. It is characterized by its two hexagonal faces that are connected by a series of trapezoidal faces. The hexagonal trapezohedron consists of 12 faces in total: 2 hexagonal faces and 10 trapezoidal faces. The properties of a hexagonal trapezohedron include: - **Vertices**: It has 12 vertices. - **Edges**: It has 30 edges.
The triangular orthobicupola is a type of Archimedean solid that is composed of two triangular cupolae (also known as "cupolas") joined at their bases, with a symmetry that allows for triangular and square faces. It is characterized by its geometry, which features: - **Vertices**: It has 24 vertices. - **Edges**: The solid consists of 36 edges.
The truncated square trapezohedron is a type of polyhedron that falls under the category of Archimedean solids. It is formed by truncating (or "cutting off") the vertices of a square trapezohedron, creating new faces in the process. ### Characteristics: - **Faces**: The truncated square trapezohedron has a total of 14 faces. There are 8 triangular faces and 6 quadrilateral faces. - **Vertices**: It has 24 vertices.
The medial rhombic triacontahedron is a type of Archimedean solid that can be characterized as a convex polyhedron. It is derived from a rhombic triacontahedron, which has 30 rhombic faces, by truncating (or cutting off) the vertices of the original solid. This truncation results in the creation of hexagonal faces at the vertices that were removed.
The order-5 truncated pentagonal hexecontahedron is a type of convex polyhedron that is classified as an Archimedean solid. It is derived from the pentagonal hexecontahedron by truncating its vertices. Specifically, the pentagonal hexecontahedron is a polyhedron composed of 60 triangular faces and 12 pentagonal faces.
The small icosacronic hexecontahedron is a convex Archimedean solid, characterized by its unique geometric properties. It has 62 faces composed of 20 equilateral triangles, 30 squares, and 12 regular pentagons. This polyhedron can be seen as a variant of the icosacron, which itself is derived from the more well-known icosahedron by expanding its structure.
The "Pentagrammic crossed-antiprism" is a type of polyhedron that belongs to the family of antiprisms. Specifically, it is a variation of the antiprism that involves a pentagram (a five-pointed star) instead of a regular polygon as its base faces. In geometrical terms, a crossed-antiprism consists of two parallel, congruent bases that are polygonal faces, connected by a set of triangular faces.
A rhombicosahedron is a type of Archimedean solid that features 62 faces: 20 of these faces are equilateral triangles and 40 are regular squares. It belongs to a class of polyhedra that is characterized by having regular polygons as faces and having vertices that are all identically structured. The rhombicosahedron has several interesting properties: - **Vertices**: It has 60 vertices. - **Edges**: It has 120 edges.
An N-ary group is a generalization of the concept of a group in abstract algebra. In group theory, a group is defined as a set equipped with a binary operation that satisfies four fundamental properties: closure, associativity, identity, and invertibility.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
