The Chevalley group $F_4\left(q\right)$ , for a prime power $q$, is a simple group of Lie type.

The ChevalleyF4( q ) command returns a permutation group isomorphic to the Chevalley group $F_4\left(q\right)$ , for $q=2$. For non-numeric values of the argument q, or for prime powers $q$ larger than $2$, a symbolic group representing the group $F_4\left(q\right)$ is returned.
