We show that if L is an extremal even unimodular lattice of rank 40r with r=1,2,3, then L is generated by its vectors of norms 4r and 4r+2. Our result is an extension of Ozeki’s result for the case r=1.

Nous montrons que, si L est un réseau unimodulaire pair extrémal de rang 40r avec r=1,2,3, alors L est engendré par ses vecteurs de normes 4r et 4r+2. Notre résultat est une extension de celui d’Ozeki pour le cas r=1.
