A non-computational approach to the gradings on $\mathfrak{f}_4$

Abstract

The fine group gradings on the exceptional Lie algebra \mathfrak{f}_4 have previously been determined by means of computational methods. A new argument is given to prove that there are just four fine gradings on \mathfrak{f}_4 .
