Heptadiminished birectified heptapeton

The heptadiminished birectified heptapeton, or ladbril, is a convex scaliform polypeton. It consists of 7 tridiminished rectified hexatera, 7 tetradiminished dodecatera, and 7 triangular-tetrahedral duoprisms. 3 tridiminished rectified hexatera, 4 tetradiminished dodecatera, and 3 triangular-tetrahedral duoprisms meet at each vertex.

It is also a convex segmentopeton, as a tridiminished rectified hexateron atop tetradiminished dodecateron.
