5900f4351000cf542c50ff47 | 5 | Problem 200: Find the 200th prime-proof sqube containing the contiguous sub-string "200" |
Description
The first five squbes are 72, 108, 200, 392, and 500.
Interestingly, 200 is also the first number for which you cannot change any single digit to make a prime; we shall call such numbers, prime-proof. The next prime-proof sqube which contains the contiguous sub-string "200" is 1992008.
Find the 200th prime-proof sqube containing the contiguous sub-string "200".
