The bicantitruncated 5-cube, also called the great birhombated penteractitriacontaditeron, great birhombipenteractitriacontaditeron, or gibrant, is a convex uniform 5-polytope. It consists of 80 triangular-square duoprisms, 32 great rhombated pentachora, and 10 truncated icositetrachora. 1 triangular-square duoprism, 2 great rhombated pentachora, and 2 truncated icositetrachora join at each vertex. As the name suggests, it is the bicantitruncation of the 5-cube, or equivalently of its dual 5-orthoplex.

Representations[edit | edit source]
A bicantitruncated 5-cube has the following Coxeter diagrams:
- o4x3x3x3o () (full symmetry)
- x3x3x3o *b3x () (D5 symmetry, as cantitruncate demipenteract)
- s4x3x3x3o () (D5 symmetry, as alternated faceting)
