The "Compound of Five Great Icosahedra" is a fascinating geometric structure in the realm of polyhedra. It is formed by arranging five great icosahedra (the dual polyhedron of the dodecahedron) around a common center. ### Characteristics: - **Vertices**: The compound has a unique vertex arrangement due to the overlapping and symmetry of the five great icosahedra.
The term "compound of four cubes" refers to a three-dimensional geometric shape constructed by combining four individual cubes in a specific arrangement. This shape can be visualized as each of the four cubes sharing faces with the others, creating a single cohesive structure. One common arrangement for the compound of four cubes is to place the cubes so that they form the shape of a larger cube (specifically, a 2x2x2 cube) when viewed from a certain angle.
The compound of the great icosahedron and the great stellated dodecahedron is known as the "stella octangula" or "octahedral compound." This compound is a three-dimensional figure formed by the intersection of two polyhedra: a great icosahedron (which is one of the Archimedean solids) and a great stellated dodecahedron (a star polyhedron).

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.Figure 1. Screenshot of the "Derivative" topic page.
