Music Macro Language (MML) is a shorthand scripting language used for music composition, particularly in computer music and programming environments. It allows users to represent music in a text format, making it easier to create, edit, and share compositions. MML provides commands to define musical elements such as notes, rhythms, volume, and effects, enabling composers to produce music via code without the need for traditional musical notation.

Mycoplasma laboratorium is a synthetic organism designed to serve as a model organism for biological research and synthetic biology. It was developed as part of efforts to create minimal cells, which are organisms stripped down to only the essential genes required for life. This organism is derived from the Mycoplasma mycoides species and was created by researchers at the J. Craig Venter Institute.

A nanocluster refers to a small group of atoms or molecules that are aggregated together, typically within the range of 1 to 100 nanometers in size. These nanoclusters can be composed of metals, semiconductors, or organic materials and are often studied for their unique physical and chemical properties that emerge at the nanoscale. Nanoclusters play an important role in various fields such as materials science, catalysis, electronics, and biotechnology.

An apeirogonal prism is a type of geometric figure that extends the concept of a prism to an infinite number of sides. Specifically, an apeirogon is a polygon with an infinite number of sides. Therefore, an apeirogonal prism consists of two parallel apeirogons (one serving as the base and the other as the top) connected by a series of vertical edges or faces.

An "augmented sphenocorona" is a type of geometric figure that belongs to the category of polyhedra. Specifically, it is a variant of the sphenocorona—one of the Archimedean solids. The term "augmented" indicates that some vertices or faces have been altered or added to the original sphenocorona to create a new shape. A sphenocorona itself is characterized by having a combination of triangular and quadrilateral faces.

An elongated bipyramid is a type of convex polyhedron that can be classified as a member of the family of bipyramids. It is formed by taking a regular polygon and adding two additional vertices that are positioned along the axis perpendicular to the polygon's plane. This elongates the resulting bipyramid compared to a standard bipyramid, which has two identical bases and equally spaced apex points above and below the center of the base.

A compound of five icosahedra refers to a geometric arrangement where five icosahedra (which are polyhedra with 20 triangular faces, 12 vertices, and 30 edges) are combined in a specific way to form a new polyhedral structure. This kind of arrangement is often explored in the context of geometric studies such as polyhedral compounds, where multiple identical polyhedra are intersected or arranged around a common center.

The compound of five octahedra, also known as the "pentaoctahedron," is a geometric structure formed by combining five octahedra in a specific arrangement. It can be viewed as a complex polyhedron or a space-filling arrangement. In polyhedral geometry, such compounds often demonstrate interesting symmetrical properties and can be visualized in three-dimensional space.

The compound of six tetrahedra is a geometric structure formed by the combination of six tetrahedra intersecting in a symmetric arrangement. In this compound, the tetrahedra are arranged in such a way that they share vertices, edges, and faces, creating a complex polyhedral configuration.

It is an interesting example of a polyhedral compound in three-dimensional space and showcases the fascinating interplay between geometry and symmetry.

The "compound of six tetrahedra" refers to a specific geometric arrangement of six tetrahedra that share a common center but can rotate freely. This structure can be visualized as a three-dimensional arrangement where pairs of tetrahedra are arranged around a central point, often showcasing the symmetrical properties of both tetrahedra and the overall compound.

The term "compound of three tetrahedra" refers to a specific geometric configuration in three-dimensional space. In this context, it typically describes a compound polyhedron composed of three tetrahedra that are arranged in such a way that they share certain vertices and edges. One common way to visualize this compound is through the arrangement where the three tetrahedra are positioned with their vertices meeting at a central point, creating a complex shape.

A compound of twelve pentagonal prisms refers to a geometric figure formed by arranging twelve pentagonal prisms in a specific way. In three-dimensional geometry, a pentagonal prism is a polyhedron with two parallel pentagonal bases connected by rectangular faces. When we talk about a compound of twelve pentagonal prisms, this can imply various configurations depending on how the prisms are arranged or combined.

The compound of two great snub icosidodecahedra is a geometric figure that consists of two instances of the great snub icosidodecahedron interpenetrating each other. The great snub icosidodecahedron is a nonconvex Archimedean solid with 92 faces (12 regular pentagons and 80 equilateral triangles), 150 edges, and 60 vertices.

A decagonal prism is a three-dimensional geometric shape that has two parallel bases in the shape of a decagon (a polygon with ten sides) and rectangular sides connecting the corresponding sides of the two bases. Key characteristics of a decagonal prism include: 1. **Bases**: The top and bottom faces are both decagons. 2. **Faces**: In addition to the two decagonal bases, the prism has ten rectangular lateral faces.

An elongated hexagonal bipyramid is a type of polyhedron that is part of the family of bipyramids. It is specifically derived from a hexagonal bipyramid by elongating it along its axis. ### Structure: - **Base Faces**: The elongated hexagonal bipyramid has two hexagonal bases connected by triangular faces. The primary difference from a regular hexagonal bipyramid is the elongation, which typically results in a pair of additional faces being introduced.

The elongated pentagonal gyrobicupola is a type of convex polyhedron that is part of the family of Archimedean solids.
