Let p be a prime number and let n be a non-zero natural number. We compute the descending Loewy series of the algebra Rn/pRn, where Rn denotes the ring of virtual ordinary characters of the symmetric group Sn.

Soit p un nombre premier et soit n un entier naturel non nul. Nous calculons la série de Loewy descendante de l'algèbre Rn/pRn, où Rn désigne l'anneau des caractères virtuels ordinaires du groupe symétrique Sn.
