Relations to other Regular Maps

Its dual is the 4-hosohedron.

It is self-Petrie dual.

It is a 2-fold cover of the hemi-di-square.

It can be 3-split to give the di-dodecagon.

It can be rectified to give the 4-lucanicohedron.

It can be diagonalised to give the tetrahedron.

It is a member of series m.
