Does anyone have any clue as to where I have gone wrong. This question is driving me mad and can't for the life of me figure out my mistake.
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.
