The general orthogonal group $GO\left(d\,n\,q\right)$ is the set of all $n\times n$ matrices over the field with $q$ elements that respect a non-singular quadratic form. The value of $d$ must be $0$ for odd $n$, or $1$ or $\mathrm{-1}$ for even $n$.

The GeneralOrthogonalGroup( d, n, q ) command returns a permutation group isomorphic to the general orthogonal group $GO\left(d\,n\,q\right)$ .

If the argument q is not a prime power (and is non-numeric), then a symbolic group representing $GO\left(d\,n\,q\right)$ is returned.

The command GO(d, n, q) is provided as an alias.

In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
