Resumo


We investigate the total coloring of fullerene nanodiscs, a subclass of cubic planar graphs with girth 5 arising in Chemistry, motivated by a conjecture about the nonexistence of a Type 2 cubic graph of girth at least 5. We give a combinatorial description and then a conformable coloring for an infinite family of fullerene nanodiscs.
