Yes, I will be able to use that - I didn't know about the "coordinates" command.  Thank you very much!

cheers,

Use the coordinates function to get the coefficients and then compose the
polynomial?


(90) -> u

            3
   (90)  3%A  + 4%A + 6
     Type: FiniteFieldExtensionByPolynomial(PrimeField 7,?**4+?**3+?*?+4*?+1)
(91) -> coordinates u

   (91)  [6,4,0,3]
                                                    Type: Vector PrimeField 7
