The hendecagonal duoprism or handip, also known as the hendecagonal-hendecagonal duoprism, the 11 duoprism or the 11-11 duoprism, is a noble uniform duoprism that consists of 22 hendecagonal prisms, with 4 joining at each vertex. It is also the 22-10 gyrochoron. It is the first in an infinite family of isogonal hendecagonal dihedral swirlchora and also the first in an infinite family of isochoric hendecagonal hosohedral swirlchora.
Vertex coordinates[edit | edit source]
The coordinates of a hendecagonal duoprism, centered at the origin and with edge length 2sin(π/11), are given by:
where j, k = 2, 4, 6, 8, 10.
