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.
