Related to this thread on <M,U> 3-cycles. Names come from this thread on my classification of BH cases.

Awesomely enough, together with the <M,U> algs, 21 of the 27 cases are 2-gen.

I'm thinking it's actually better than 21/27 = 77.8%. Lemme do a quick calculation.

Edit: WTF it's 384/440 cases that are 2-gen, that's 87.3% O_o (In case you can't do the math, only 56/440 cases are not 2-gen-able.)
