[GAP Forum] Indeterminates of polynomial function

Dear Forum, Dear Kit Nurlan Lessenger-Anclecharly,

OccuringVariableIndices(f);

will return a list of the index numbers of the occurring variables, and

List(OccuringVariableIndices(f),x->UnivariatePolynomialByCoefficients(CoefficientsFamily(FamilyObj(f)),[0,1],x));

will return a list of the actual variables.

Regards,
