Hendecagrammic-great hendecagrammic duoprism

The hendecagrammic-great hendecagrammic duoprism, also known as the 11/3-11/4 duoprism, is a uniform duoprism that consists of 11 hendecagrammic prisms and 11 great hendecagrammic prisms, with 2 of each meeting at each vertex.

The name can also refer to the small hendecagrammic-great hendecagrammic duoprism, the great hendecagrammic duoprism, or the great hendecagrammic-grand hendecagrammic duoprism.
