The icosiheptaheptacontadipetic prism or jakip is a prismatic uniform polyexon that consists of 2 icosiheptaheptacontadipeta, 27 triacontaditeric prisms, and 72 hexateric prisms as facets. Each vertex joins 1 icosiheptaheptacontadipeton, 10 triacontaditeric prisms, and 16 hexateric prisms. As the name suggests, it is a prism based on the icosiheptaheptacontadipeton, which also makes it a convex segmentoexon.
Vertex coordinates[edit | edit source]
The vertices of an icosiheptaheptacontadipetic prism of edge length 1, centered at the origin, are given by:
- and all even sign changes of the first five coordinates,
- and all permutations of first 5 coordinates.
