{6,4∣3} is a regular skew polyhedron in 4-space. Its faces are precisely the hexagonal faces of the decachoron.

Vertex coordinates[edit | edit source]

Its vertex coordinates are the same as those of the decachoron.

{6,4∣3} is the smallest of several skew polyhedra of the form {6,4∣n}, and the only finite case.

There is a direct correspondence between these and the regular polyhedra with triangular faces: {6,4∣n} contains truncated {3,n} polyhedra as pseudocells.
