The 6-cube (OBSA: ax), also called the hexeract or dodecapeton, is a regular 6-polytope. It has twelve 5-cubes as facets, joining 6 to a vertex. It is the 6-dimensional hypercube.

It is also a 5-cubic prism, a cubic duoprism, square trioprism, dodecahedron-small stellated dodecahedral gyropeton, and 12-3-5 gyropeton.

It can be alternated into a 6-demicube, which is uniform.

Representations[edit | edit source]

A 6-cube has the following Coxeter diagrams:

  • x4o3o3o3o3o () (full symmetry)
  • x4o3o2x4o3o () (B3×B3 symmetry, cubic duoprism)
  • x4o2x4o3o3o () (B4×B2 symmetry, square-tesseractic duoprism)
  • x2x4o3o3o3o () (B5×B1 symmetry, 5-cube prism)
  • x4o2x4o2x4o () (B2×B2×B2 symmetry, square trioprism)
  • x2x4o2x4o3o () (B3×B3×A1 symmetry, square-cubic duoprismatic prism)
  • x2x2x4o3o3o () (B4×K2 symmetry, tesseract prismatic prism)
  • x2x2x4o2x4o () (B2×B2×K2 symmetry, square duoprismatic prismatic prism)
  • x2x2x2x4o3o () (B3×K3 symmetry, cubic prism prism prism)
  • x2x2x2x2x4o () (B2×K4 symmetry, five dimensions different)
