In experimenting with the Chor-Rivest knapsack cryptosystem, I have the problem of adding two polynomials: one is the defining polynomial of the field, and the other is a field element.
But the command
definingPolynomial()$F+u
produces the error
>> Error detected within library code: coerce: element doesn't belong to smaller field
which I don't understand. What I need to do is to force u to be treated as an "ordinary" polynomial, rather than as a field element...
