#### Abstract

A *fullerene* is an all carbon molecule that can be represented by a 3-regular planar graph with face sizes five or six. A subset $S$ of the vertices of a graph forms an independent set if the vertices of $S$ are pairwise non-adjacent. The problem of finding the size of a maximum *independent set* of a graph is NP-complete when restricted to 3-regular graphs. In contrast, for fullerenes we have designed an algorithm that solves the problem in linear time.
