Decagonal-square antiprismatic duoprism

The decagonal-square antiprismatic duoprism or dasquap is a convex uniform duoprism that consists of 10 square antiprismatic prisms, 2 square-decagonal duoprisms and 8 triangular-decagonal duoprisms. Each vertex joins 2 square antiprismatic prisms, 3 triangular-decagonal duoprisms, and 1 square-decagonal duoprism.
