About: Compound of four tetrahedra

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In geometry, a compound of four tetrahedra can be constructed by four tetrahedra in a number of different symmetry positions. One compound can be constructed rotating a tetrahedron by 45 degree turns along an axis of the middle of an edge. It has dihedral symmetry, D4 It has the same vertex arrangement as the convex octagonal prism.
