An application of Steinberg’s construction of twisted groups

Eivind Stensholt

Vol. 55 (1974), No. 2, 595–618
Abstract

The construction of the twisted groups uses automorphisms of certain Chevalley groups derived from symmetries of the Dynkin diagrams. This paper applies the same method to the symmetries of the extended Dynkin diagrams. The groups so constructed turn out to be other Chevalley groups exhibited in a way which let a particular subgroup structure appear.
