In five-dimensional geometry, a runcinated 5-orthoplex is a convex uniform 5-polytope with 3rd order truncation (runcination) of the regular 5-orthoplex. There are 8 runcinations of the 5-orthoplex with permutations of truncations, and cantellations. Four are more simply constructed relative to the 5-cube. {{TOC left}}{{-}}Runcinated 5-orthoplexRuncinated 5-orthoplex | Type | Uniform 5-polytope | Schläfli symbol | t0,3{3,3,3,4} | Coxeter-Dynkin diagram | {{CDD | 3|node | node|3|node_1|4|node}} {{CDD | 3|node | node|split1|nodes_11} | 4-faces | 162 | Cells | 1200 | Faces | 2160 | Edges | 1440 | Vertices | 320 | Vertex figure | | Coxeter group | B5 [4,3,3,3] D5 [32,1,1] | Properties | convex |
