Standard generators

Standard generators of G2(4) are a, b where a is in class 2A, b is in class 5C/D, ab has order 13 and abb has order 13. Alternatively: a is in class 2A, b has order 5, ab has order 13, abb has order 13 and ababb has order 15.

Standard generators of 2.G2(4) are preimages A, B where B has order 5 and AB has order 13.

Standard generators of G2(4):2 are c, d where c is in class 2C, d is in class 4D, cd has order 13 and cdcddd has order 6.

Standard generators of 2.G2(4).2 are preimages C, D where CD has order 13.

Standard generators of 2.G2(4).2 (isoclinic) are preimages C, D where CD has order 13.
