The skewed Petrial muoctahedron is a regular skew polyhedron in 3-dimensional Euclidean space.

Vertex coordinates[edit | edit source]

The vertex coordinates of a skewed Petrial muoctahedron with unit edge length can be given as:

  • (i , j , k ),

where two or more of i , j  and k  are odd.

The relations between the skewed Petrial muoctahedron and several other skew apeirohedra.

As its name suggests, it can be constructed as the skewing of the Petrial muoctahedron. It follows from the definition of skewing that it, can also be constructed as the dual of the Petrial halved mucube.

It can be constructed as the rectification of the mutetrahedron, by applying a generalized Wythoffian construction. The geometric construction, (i.e. placing a vertex at the midpoints of edges etc.) yields a different non-regular polytope.
