Heptagrammic-hendecagonal duoprism

The heptagrammic-hendecagonal duoprism, also known as the 7/2-11 duoprism, is a uniform duoprism that consists of 11 heptagrammic prisms and 7 hendecagonal prisms, with 2 of each meeting at each vertex.

The name can also refer to the great heptagrammic-hendecagonal duoprism.
