Crikey, Listener 4503 was tricky, wasn’t it?  I eventually succumbed to writing a few of those functions that I had always meant to for years, for future numerical puzzle-setting.  You perhaps know the sort: isprime() to test if the number in brackets is prime and so on.  The functions  istriang() and isdiag() soon followed.  Did it help much here?  Probably not.  In fact the most re-usable one was getdigit(number, digit) to let me select any single digit within a number e.g. to compare it with another, check if it is odd, …

My suspicion is that many seasoned numerical setters and solvers must have some of these at their fingertips and more than likely a lot more – though this was the first puzzle that finally encouraged me.

I think it was about Sunday lunchtime when I finally cracked L4503, having eventually used the final 5 lines of the Preamble for the first time to determine whether my LOI at 26ac should be 522 or 524.

I was left with the worrying suspicion that their surely must have been a much more straightforward Solution Path than mine.  The Mersenne primes helped get an initial toehold but some of the properties – especially for me ‘f’ and ‘i’ – seemed to give little info until right at the end.

But I did think that the hidden message telling us to indicate those different ways to reach that special number 4503 was good.  There were, I think:

  • 19 x 3 x 79
  • 57 x 79
  • 19 x 237 and even
  • 18012 / 4

Unbelievably well hidden, I hear you say.  My finished article therefore looked like this:

What was that?  You didn’t spot the hidden message??

    I always enjoy your uncovering of the truth behind these puzzles. Somehow, even when I submit the correct grid, I don’t access the essential (and some would say unhinged) reality.

    I have a bunch of those functions you mention hanging around from previous numerics but managed not to use them at all this time around!
