Dear Forum,

Obviously, there is an error in the Coefficients routine for finite
fields, as this example shows:

gap> V:=VectorSpace([ Z(5)^0, Z(5^2)^2 ],GF(5));
VectorSpace( [ Z(5)^0, Z(5^2)^2 ], GF(5) )
gap> b:=Base(V);
[ Z(5)^0, Z(5^2)^2 ]
gap> c:=Coefficients(V,Z(5)^3);
[ Z(5)^2, 0*Z(5) ]
gap> c[1]*b[1]+c[2]*b[2];
Z(5)^2

However FiniteFieldOps.Coefficients (which I could not find in the manual)
seems to work as expected and can be used to replace the faulty routine.
