This is another of those letters-for-digits Enigmas, where each digit is
consistently replaced by a letter, different letters being used for different
digits. I can tell you that

NINE is divisible by 9

EIGHT is a perfect cube

and PRIME is prime.

Playing about with prime numbers can take ages, but with aid of a calculator
and efficient thinking you can, within ten minutes tell me what TEN is.

Correction

STEVE HUGHES was the winner of Enigma 866 and not of No 867 as stated
(Enigma, 27 April). And it will be best if entries to that week’s puzzle are
marked Enigma 872 and not 873 as suggested.
