It's just the group of integers modulo 6... The group operation is addition.

Yes, residues are the same thing. Everything is done mod 6 here, so 5 + 5 = 4, 2[sup]5[/sup] = 2, etc. From this you can see that it is actually a group.

If you want to be really explicit, you write them as:
{[0], [1], [2], [3], [4], [5]}
The equivalence classes of 0, 1, 2, 3, 4, 5, and 6. But when you start working with them, you very quickly find this extremely annoying, and so you drop the [].
