    Z/nmZ for (n,m)=1, with invertible elements highlighted and elements enumerated in-order (i.e., element k is in cell (k\mod n,k\mod n))?
    Presumably a continuation of the CRT series, and the omission of the noncoprime cases is because in those cases the additive group is acyclic, so there is no natural labelling by integers?
