Amicable pairs (x, y) under the following transform: x mod (2, 3, 4, ..., i+1) = (b_i, b_i-1, ..., b_1), where b_1, b_2, ..., b_i are the digits of y, with MSD(y) = b_i and LSD(y) = b_1; y mod (2, 3, 4, ..., j+1) = (c_j, c_j-1, ..., c_1), where c_1, c_2, ..., c_j are the digits of x, with MSD(x) = c_j and LSD(x) = c_1.
