Dear GAP forum, I have run the following codes:
*gap> k:=GF(2^2);;gap>T:=MappingByFunction(k,k,t->t^2);;gap> x:=Indeterminate(k,"x");gap> Image(T,x);Error, usage: Image(<map>), Image(<map>,<elm>), Image(<map>,<coll>)* It appears the error because x is not an element of k *gap> x in k;* *false* Could you show me how to compute the image of a variable under a map? Thank you very much. Best regards, Huta _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
