They do implement the same basic algorithm. However, Robert worked
from McKay's paper describing the algorithm, which was approximately
state-of-the-art when he wrote the paper (but of course, the community
tends to eschew optimizations as superfluous to the math, so...).
Also, nauty has some pret

Yes
Did you rebuild the cached workspace? I.e. "rm -rf ~/.sage/gap". If you
manually install a package in GAP then we can't know that a package was
added...

Hi,
I would like to do semidirect product of PGL(3,4) with Z_2. The homomorphism
phi: z_2 --> Aut(PGL(3,4) is defined as follows. phi(-1)(A) = (A^{-1})^t. That
is A inverse transpose.
If I can directly find the projective semilinear group P Gamma L(3,4)
using sage, then it is very helpfull
