Neil Sloane, OEIS Foundation

Abstract

It was a busy summer. 1. Having raised the necessary endowment, the OEIS is now looking to hire a managing editor. 2. Dampening Down Diverging Series: making the harmonic series and others converge. 3. Covering a sequence (e.g. (n,prime(n))) with straight lines. 4. An innocent-looking definition leads to the Riesel and Sierpinski problems and some astronomical primes. (With thanks to M. Alekseyev, L. Blomberg, L. Brown, D. McCarty, B. McEachen, R. Sigrist, et al.)
