[MysticCat]

In Phi Mu Alpha Sinfonia, a recolonized chapter uses the same letters as given in the original charter -- no deuteron or other distinguishing designation.

I think from what I've seen in materials Ms. MysticCat has that Kappa Kappa Gamma does use deuteron to indicate a rechartered chapter. (I'm sure a Kappa can and will correct me if I'm wrong about that.)
