1013 is the smallest 4-digit prime that starts a run of seven
consecutive primes where between any two successive primes,
exactly one digit changes (i.e., 1013, 1019, 1021, 1031,
1033, 1039, 1049). Can you find a run of more than seven
consecutive primes where between any two successive primes
exactly one digit changes? [Loungrides]
