Description
Examples
AffineGeneralLinearGroup( n, q )
AGL( n, q )
n
-
a positive integer
q
a prime power greater than 1
The affine general linear group AGLn,q is the semi-direct product of the general linear group GLn,q with the natural module of dimension n over the field with q elements.
The AffineGeneralLinearGroup command produces a permutation group isomorphic to the group AGLn,q.
