Your number 98765431 is not pandigital according to the definition in the problem statement; having a length of 8 digits it should contain all digits from 1 to 8 exactly once. :wink:

I could just tell you, but that 'rule' is really not hard to google. Give it a try :)

Just in case that was in response to my post, I was merely giving @ethereal1m a hint (he was trying 9 digit pandigital primes).

from my calculation but it's wrong.
This answer is wrong as an 8 digit pandigital number must consist of the digits 1-8.
