By the Three Graces we refer, following J.-L. Loday, to the algebraic
operads Ass, Com, and Lie, each generated by a single binary
operation; algebras over these operads are respectively associative,
commutative associative, and Lie. We classify all distributive laws
(in the categorical sense of Beck) between these three operads. Some
of our results depend on the computer algebra system Maple,
especially its packages
Keywords: Algebraic operads, distributive laws, Koszul duality, associative algebras, commutative associative algebras, Lie algebras, Poisson algebras, linear algebra over polynomial rings, Gr\"obner bases for polynomial ideals, computer algebra
