It took me a while to understand what the numbers were actually trying to indicate (in part because I'm used to numbers in sheet music being suggestions of which finger should play the given note). If I understand correctly now, are you numbering zero-indexed with C as the beginning (0) and B as the end (Y), as a proxy for remembering which key notes are meant to be played in?
That's right - so a major triad in C would be (0-4-7), or a B-flat minor triad would be (X-1-5).
It's not required that the pitch notation is absolute though, e.g. you can transpose the numeric notation to any key (e.g., use A == 0 instead of C ==0)
What does "isomorphic" mean?
