 Nov10 awarded Tumbleweed Oct27 awarded Scholar Oct27 accepted Prime factorization knowing n and Euler's function Oct27 asked Prime factorization knowing n and Euler's function Oct16 comment Generator polynomial Is it possible this process? I know that factorization of $(x^{12}+1)$ is $(x+1)^4(x^2+x+1)$ and I need to find the product of factor of degree $n-k$ (in this case 7). So the generator polynomial can be $x^7+x^5+x^4+x^3+x^2+x+1$. Is it true? Can I get a parity check polynomial from this generator polynomial? Oct16 awarded Editor Oct16 revised Generator polynomial edited body Oct16 asked Generator polynomial Oct15 comment Factorization of $(x^7-1)$ into irreducible factors over $GF(4)$ So I have $(x-1)(x^6+x^5+x^4+x^3+x^2+x+1)$.
