Abstract:

A table of primes of the form $({a^n} - 1)/(a - 1)$ for values of a and n such that $3 \leqslant a \leqslant 12$, $2 \leqslant n \leqslant 1000$ is presented. A description is given of the techniques used to obtain this table, and some numbers such as $({10^{1031}} - 1)/9$ which are pseudoprime but whose primality is not yet rigorously established are also discussed.
