Abstract: These tables give the complete factorization of ${x^n} - 1$ over ${\text{GF}}(q),q = {p^a},2 \leqslant n \leqslant d$ as below, together with the Euler $\Phi$ -function of ${x^n} - 1$ whenever $\Phi ({x^n} - 1) < {10^8}$ .

$\begin{displaymath}\begin{array}{*{20}{c}} {q = 2;d = 32} \hfill & {q = 3;d = 27... ... {q = 7;d = 15} \hfill & {q = 23;d = 10} \hfill \\ \end{array} \end{displaymath}$
