Extended calculations of a special Harmonic number
Abstract
The search for values of p for which the Harmonic numbers H p/6 vanish mod p, carried to p < 600,000 by Schwindt in 1983, is extended here to p < 149,250,000,000,000, and two new solutions are reported. (These results can now be found in the Online Encyclopedia of Integer Sequences, entry no.\ A238201.)
