Hi,
I have the following problem:
M=MatrixSpace(GF(2^2,'a'),5)
A=M.random_element()
N=MatrixSpace(GF(2^4,'a'),5)
N(A)
TypeError: unable to coerce from a finite field other than the prime
subfield
Is there a simple way around non prime subfield embeddings?
Thanks,

Hi,
suppose I have a field embedding A = GF(2^4) -> B = GF(2^20) say,
and I pick a homomorphism phi from C=A.Hom(GF(2^20,'x')), e.g.
sage: phi
Ring morphism:
From: Finite Field in x of size 2^4
To: Finite Field in x of size 2^20
Defn: x |--> x^19 + x^14 + x^13 + x^12 + x^10
