In honour of the memory of Richard Crandall<\/a> (1947-2012), I\u00a0have devised a puzzle on prime numbers obtained from moments\u00a0<\/a>of Bessel functions<\/a>:<\/span><\/p>\n

I commend this puzzle to Richard’s many colleagues, noting\u00a0that “hand-to-hand combat with thousand-digit integrals” may\u00a0be insufficient to solve it, without using brain as well as\u00a0brawn. I have prepared a solution, together with a heuristic\u00a0analysis that I think Richard would have liked. This will be\u00a0released at the end of the year. Until then, happy puzzling.<\/p>\n

Here is the mathematical description of the puzzle:
