  Let G be a finite group, Irr(G) the set of all irreducible complex characters
of G and X \in Irr(G). Let also cod(X) = |G : kerX|/X(1) and cod(G) = {cod(X) |
X \in Irr(G)}. In this note, we show that the simple group PSL(2, q), for a
prime power q > 3, is uniquely determined by the set of its codegree.
