Abstract:
We give a result on Cartan invariants of the group algebra  of a finite group  over an algebraically closed field  , which implies that if the Loewy length (socle length) of the projective indecomposable  -module corresponding to the trivial  -module is four, then  has characteristic 2. The proof is independent of the classification of finite simple groups.
