**From David Broadhurst, October 5, 2015**.

In honour of the memory of Richard Crandall (1947-2012), I have devised a puzzle on prime numbers obtained from moments of Bessel functions:

I commend this puzzle to Richard’s many colleagues, noting that “hand-to-hand combat with thousand-digit integrals” may be insufficient to solve it, without using brain as well as brawn. I have prepared a solution, together with a heuristic analysis that I think Richard would have liked. This will be released at the end of the year. Until then, happy puzzling.

Here is the mathematical description of the puzzle:
