A trinitarian question of relation?

I fear if I ask this question on Puritanboard I will be banned, so I will ask it here.

If persons = relations, as Thomas says, then does the converse hold:

(P1) Relations = Persons

This raises the next question:

(P2) Is now the relation between the person yet another person?

If you keep repeating this you have the infinite hypostases of Gnosticism.
