Hi, I have defined octonions over field o:=OctaveAlgebra(GF(7));
Next create set of some invertible elements belonging to some subalgebra. And I wanted to see what group is generated by invertible elements in this subalgebra. Unfortunately I cannot use "Group" function, because I obtain error "no groups of cyclotomics allowed because of incomatible ^". I am using GAP version 4.8.8. This subalgebra is associative, because it is generated by two elements. Therefore invertible elements should form a group. Do you have any advice or workaround how could I test my group ? I wanted to use StructureDescription. These are small groups of size 294,336,392 and 686. gap> g1:=Group([1..5],k->Random(c1i)); #I no groups of cyclotomics allowed because of incompatible ^ Error, usage: Group(<gen>,...), Group(<gens>), Group(<gens>,<id>) called from <function "Group">( <arguments> ) called from read-eval loop at line 74 of *stdin* you can 'quit;' to quit to outer loop, or you can 'return;' to continue brk> quit; Regards, Marek _______________________________________________ Forum mailing list Forum@gap-system.org https://mail.gap-system.org/mailman/listinfo/forum
