We completely determine commutative semigroup varieties that are distributive, standard or neutral elements of the lattice of all commutative semigroup varieties. In particular, it turns out that the properties of being a distributive element and of being a standard element in this lattice are equivalent.
Keywords: semigroup, variety, lattice, distributive element, standard element.
Mots-clés : neutral element
