Abstract: | To supplement existing data, solutions of are tabulated for primes with and . For , five new solutions are presented. One of these, for , also satisfies the ``reverse' congruence . An effective procedure for searching for such ``double solutions' is described and applied to the range , . Previous to this, congruences are generally considered for any and fixed prime to see where the smallest prime solution occurs. |
