Small biprismatotetradecapeton

The small biprismatotetradecapeton or biruncinated heptapeton, also called the biruncinated 6-simplex, is a convex uniform polypeton. 4 small prismated hexatera and 6 triangular-octahedral duoprisms join at each vertex. As the name suggests, it is the biruncination of the heptapeton.
