Great biprismatotetradecapeton

The great biprismatotetradecapeton or biruncicantitruncated heptapeton, also called the biruncicantitruncated 6-simplex, is a convex uniform polypeton. 4 great prismated hexatera and 2 triangular-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the biruncicantitruncation of the heptapeton.
