Cellitruncated heptapeton

The cellitruncated heptapeton or catal, also called the steritruncated heptapeton or steritruncated 6-simplex, is a convex uniform polypeton. It consists of 7 celliprismated hexatera, 7 small prismated hexatera, 21 rectified pentachoric prisms, 35 hexagonal-octahedral duoprisms, and 35 triangular-truncated tetrahedral duoprisms. 2 celliprismated hexatera, 1 small prismated hexateron, 1 rectified pentachoric prism, 3 hexagonal-octahedral duoprisms, and 3 triangular-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the steritruncation of the heptapeton.
