| Oct 11, 2015 at 17:06 | comment | added | Dave Witte Morris | I don't think this is true. If $\sigma$ is the nontrivial automorphism $x \mapsto x^{-1}$ of $\mathbb{G}_m$, then the semidirect product $\mathbb{G}_m \rtimes \langle \sigma \rangle$ seems to be a counterexample. (Groups of multiplicative type are abelian.) | |
