Dear Forum, I was wondering if it is possible to recover the group G2(3) directly from the octonion algebra O:=OctaveAlgebra(GF(3)). I’ve tried to use End(GF(3),O) and then select the bijective maps that respect the multiplication, but it seems to hard for GAP. Is there any way to construct the automorphism group of an algebra?
