Hello, I am generating a random polynomial over the field GF(2^6), and when I print it, I cannot undertstand the values of certain factors:
The polynomial looks like this: x^9 + (z6^5 + z6^3)*x + z6^4 + z6^2 + z6 What do z6, z6^5 mean? I searched but I was unable to find an answer in the docs.
This arises when constructing the field.
sage: F = GF(64)
sage: F
Finite Field in z6 of size 2^6
The element "z6" is the generator of F over the prime field GF(2): the command F.gen() will return z6, and the documentation returned by F.gen?says 'Return a generator of "self" over its prime field, which is a root of "self.modulus()".' The documentation returned by F.modulus? says 'Return the minimal polynomial of the generator of "self" over the prime finite field.' In this case F.modulus() returns x^6 + x^4 + x^3 + x + 1.
