I have used log_repr() and expect that it return y of equation x^y = z. I
also believed hat k.gen() return generator of the field.
Now I must use following construction for solving my problem
sage: R.x=ZZ[]
sage: k=GF(2^8,name='a',modulus=x^8+x^4+x^3+x+1)
sage: a = k.multiplicative_generator()
Hi,
K.gen() returns the thing we represent field elements in, but not necessarily
the field generator.
1) However, the documentation is wrong:
Return a generator of self. All elements x of self are expressed as
log_{self.gen()}(p) internally
This should be fixed and a reference to
PARI doesn't have a log_repr() to begin with, so I don't see how that's
relevant.

Yes, never mind my comment.

Hello all.
I have encountered the following problem In Sage 5.0:
sage: R.x=ZZ[]
sage: k=GF(2^8,name='a',modulus=x^8+x^4+x^3+x+1)
sage: k(ZZ(3).digits(2))
a + 1
sage: k.gen()^ZZ(k(ZZ(3).digits(2)).log_repr())
a
sage: k.gen()^ZZ(k(ZZ(3).digits(2)).log_repr()) == k(ZZ(3).digits(2))
False
