Look at the prime number 3137. If one digit at a time is deleted, we generate the "sub-numbers" 137, 337, 317, 313. All four new of the sub-numbers are also prime,or sub-primes.
Are there any more 4-digit primes which behave in exactly the same way? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
