1. ## Edge Side Orbits

On the sheet, construct the edge side orbits under the action of the full symmetry of the group T_1. Then find the IH number

Now I thought had done this correct but when it came to find the IH number after finding the incidence number I was left with seven symbols and no IH number has seven symbols.

Can someone give me a clue as to where I have gone wrong.

Thanx
