Abstract:

If p is an irregular prime, $p < 8000$, then the indices 2n for which the Bernoulli quotients ${B_{2n}}/2n$ are divisible by ${p^2}$ are completely characterized. In particular, it is always true that $2n > p$ and that ${B_{2n}}/2n\;\nequiv ({B_{2n + p - 1}}/2n + p - 1)\pmod {p^2}$ if (p,2n) is an irregular pair. As a result, we obtain another verification that the cyclotomic invariants ${\mu _p}$ of Iwasawa all vanish for primes $p < 8000$.
