The steriruncitruncated 6-simplex, also called the steriruncitruncated heptapeton, celliprismatotruncated heptapeton, or captal, is a convex uniform 6-polytope. It consists of 7 steriruncitruncated 5-simplices, 7 runcicantellated 5-simplices, 21 decachoric prisms, 35 triangular-truncated tetrahedral duoprisms, and 35 hexagonal-truncated tetrahedral duoprisms. 2 steriruncitruncated 5-simplices, 1 runcicantellated 5-simplex, 1 decachoric prism, 1 triangular-truncated tetrahedral duoprism, and 2 hexagonal-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the steriruncitruncation of the 6-simplex.
