Standard generators

Standard generators of L2(17) are a, b where a has order 2, b has order 3 and ab has order 17.

Standard generators of 2.L2(17) are preimages A, B where B has order 3 and AB has order 17.

Standard generators of L2(17):2 = PGL2(17) are c, d where c is in class 2B, d has order 3, cd has order 16 (necessarily in class 16B) and cdcdd has order 4.

Standard generators of 2.L2(17).2 are preimages C, D where D has order 3.
