The app divides the number 607920 / 51 = 11920. The gwnum lib has a bug somewhere and the dev is informed.

At the moment only S51 is affected.

Base S51 will be stopped for the time being after 35-37k is done, the tests are correct with the divided numbers but primes cant be removed from the sievefile.

All affected tests must be convert to the correct values. This takes time.
