Chevalley Groups

The Chevalley groups are the finite simple groups of Lie-type. They include four families of linear simple groups: PSL(n,q) (the projective special linear group), PSU(n,q) (the projective special unitary group), PSp(2n,q) (the projective symplectic group), and POmega^epsilon(n,q).

The following table lists exceptional (untwisted) Chevalley groups.
