Hmm how to explain... Actually, I replace by m, n and p because it was redundant and really confusing.

It's equivalent to say "the first coordinate of the image of a triplet by T is the sum of its two last coordinates".

It sounds strange to me... Because once you replace with m, n or p, you don't have to say "I'll replace it by...".
