Here's a problem I don't think I have seen asked before:


Another way of asking the problem would be: How large is the subgroup
generated by just five of the six quarter twists.

According to the Fusrt-Hopcroft-Luks algorithm, they are the same
size. I would appreciate Hoey and Saxe to confirm this (I think I
have all the bugs out of my code). Sorry for such a brute force
method, but it only took a few minutes.
