A127368 which is triangular X if X,Y are coprime might have a typo in
the last two sample values. The table at http://oeis.org/A127368/table
ends
1 0 3 0 0 0 7 9 0
but I wonder if it's meant to be
1 0 3 0 0 0 7 0 9 0
ie. either the last two values swapped or an extra 0 inserted. Either
way making position 10,8 have value 0 because 10,8 has a common factor.
