It's not quite clear what group structure you have on each of the integer sets I_i.
Probably, they form a group under addition modulo m_i ?
In the latter case, your group is the direct product of cyclic groups of
orders m_1 and m_2 and GAP can quite happily work with them.
Have a look at CyclicGroup and DirectProduct.
