Pentagonal-hexagonal antiprismatic duoprism

The pentagonal-hexagonal antiprismatic duoprism or pehap is a convex uniform duoprism that consists of 5 hexagonal antiprismatic prisms, 2 pentagonal-hexagonal duoprisms, and 12 triangular-pentagonal duoprisms. Each vertex joins 2 hexagonal antiprismatic prisms, 3 triangular-pentagonal duoprisms, and 1 pentagonal-hexagonal duoprism.
