COMMENTS
| One of the other two less significant digits (and possibly both) will also differ.
Most of the Ormiston prime pairs referenced in A069567 differ only in the two least significant digits.
|
|
|
EXAMPLE
| 18379 is not included since the next prime 18397 does not change the hundreds digit even though the same digits are used.
64091 is included because the next prime is 64109 which uses the same digits and the hundreds digit is the most significant digit changed.
29610901 is not included because the next prime is 29611009 which differs in the thousands digit.
