(In reply to re: manual solution to bonus is wrong by broll)

I have just looked up Enigma Number 1643 (New Scientist, April 20, 2011.  )

It is entirely different problem, addressing divisibility, with totally different answer.

Mine was independently created by me and some by-products are already in the queue -

I am sure, broll, that you will both identify them and solve them.
