Relations to other Regular Maps

Its dual is S2:{8,4}.

Its Petrie dual is S3:{8,8}4.

It can be 2-fold covered to give S3:{4,8|4}.
It can be 2-fold covered to give S3:{4,8|2}.

It can be rectified to give rectification of S2:{8,4}.

It can be derived by stellation (with path <1,-1>) from S2:{3,8}. The density of the stellation is 3.

It is a member of series h.
