 SpecialLinearGroup
 construct a permutation group isomorphic to a special linear group

 Calling Sequence SpecialLinearGroup(n, q) SL(n, q)

Parameters

 n - a positive integer q - power of a prime number

Description

 • The special linear group $SL\left(n,q\right)$ is the set of all $n×n$ nonsingular matrices over a finite field of size $q$ whose determinant is $1$.
 • The SpecialLinearGroup( n, q ) command returns a permutation group isomorphic to the special linear group $SL\left(n,q\right)$ for values of n and q in the implemented ranges.
 • The implemented ranges for the parameters n and q are as follows:

 $n=2$ $q\le 100$ $n=3$ $q\le 20$ $n=4$ $q\le 10$ $n=5$ $q\le 5$ $n=6,7,8,9,10$ $q=2$

 • If either or both of the parameters n and q is non-numeric, then a symbolic group representing the indicated special linear group is returned.
 • In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
