Standard generators

Standard generators of J3 are a, b where a has order 2, b is in class 3A, ab has order 19 and ababb has order 9.

Standard generators of 3.J3 are preimages A, B where A has order 2 and B is in class +3A. Alternatively: A has order 2 and ABABABB has order 17.

Standard generators of J3:2 are c, d where c is in class 2B, d is in class 3A, cd has order 24 and cdcdd has order 9.

Standard generators of 3.J3:2 are preimages C, D where D is in class +3A.
