## Standard generators

Standard generators of U3(5) are a, b where a has order 3, b is in class 5A and ab has order 7.

Standard generators of 3.U3(5) are preimages A, B where B has order 5 and AB has order 7.

Standard generators of U3(5):2 are c, d where c is in class 2B, d is in class 4A, cd has order 10 and cdcdddcdd has order 2.

Standard generators of 3.U3(5):2 are preimages C, D where D has order 4.

Standard generators of U3(5):3 are e, f where e is in class 2A, f is in class 3C/C' and ef has order 15.

Standard generators of 3.U3(5).3 are preimages E, F where E has order 2.

Standard generators of U3(5):S3 are g, h where g is in class 2B, h is in class 3C, gh has order 8 and ghghh has order 12.

Standard generators of 3.U3(5).S3 are preimages G, H.
