Dear Gap-forum,

I have found, maybe not a bug, but at least an oddity in GAP3.4.4

as the following log illustrates:

gap> q:=X(CF(1));q.name:="q";Factors(q^2-1); X(Rationals) "q" [ q - 1, q + 1 ] gap> q:=X(CF(2));q.name:="q";Factors(q^2-1); X(CF(1)) "q" Error, sorry, can not factor <r> in the ring <R> in R.operations.Factors( R, r ) called from Factors( q ^ 2 - 1 ) called from main loop brk>

Best regards,

Jean MICHEL
