Dear all
I am getting trouble on how i can find order of an element in a quotient
polynomial ring USING SAGE:
1.Example, I have this code in sage I want to find the order of polynomial
h(x) in Quotient ring $\mathbb{F}_{2}[x]/<x^3+1>$.
F.<x>=GF(2)[]
Q.<x>=F.quotient(x^3+1)
h=Q.f=x+1
2. Does it need to x^3+1 to be irreducible in $\mathbb{F}_{2}[x]$?
Thanks
regards
G.Chacha
