Relations to other Regular Maps

Its dual is C7:{9,4}.

Its Petrie dual is S6:{9,9}.

It can be 2-fold covered to give S6:{4,9}.

List of regular maps in non-orientable genus 7.

Underlying Graph

Its skeleton is 3 . K4.


Each face is complementary to (as well as antipodal to) a Petrie polygon. For a face-Petrie polygon pair, each edge is a member of one or the other.
