 Compound of three tetrahedra

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.
