well, here is the same information when the target number has a factor of 2 or 3. The ratio pair (12,4) is evidently repeated, the two cases are $1,10 \pmod {12}.$ 


Oh, note that multiples of $9$ are never represented primitively. That is fine, the number of representations is exactly the same as the number of representations of $M/9.$

It won't let me put the whole thing. I will put up to 36 mod 72, although 36 itself is ruled out
