I have tried to use GO(-1,6,2) but encountered

gap> matGroup := GeneralOrthogonalGroup(-1,6,2);

gap> InvariantQuadraticForm(matGroup);

rec(

matrix := [ <an immutable GF2 vector of length 6>, <an immutable GF2

vector of length 6>, <an immutable GF2 vector of length 6>,

<an immutable GF2 vector of length 6>,

<an immutable GF2 vector of length 6>,

<an immutable GF2 vector of length 6> ] )

However when I choose q=3 or 5 I get the quadratic form which gives the

group, and then I can do all kinds of computations. How do I generate the

group when q is even?

Thanks,

shaoyu
