Group of Lie type
（重定向自Chevalley group）
In mathematics, specifically in group theory, a group of Lie type is a group closely related to the group, G(k), of rational points of a reductive linear algebraic group, G, with values in the field, k. Finite groups of Lie type give the bulk of non-abelian finite simple groups. Special cases include the classical groups, the Chevalley groups, the Steinberg groups, and the Suzuki–Ree groups.
