We give a combinatorial overview of the plethystic Hopf algebra structure of the MacMahon relying on the construction of a plethystic Hopf algebra from any alphabet of neutral letters obtained by G.-C. Rota and J. Stein. A MacMahon symmetric function is a formal power series of bounded degree, in a finite number of infinite alphabets, that is invariant under the diagonal action of the symmetric group.
