EXAMPLE
|
The pairs (5,7) and (7,11) are omitted, albeit are both consecutive primes and consecutive safe primes, however their distances (2 and 4) are singular. Cases [467,439] and [20738027,20738039] are pairs are both consecutive of consecutive primes and consecutive safe primes in minimal distance=12. The corresponding twins of Sophie-Germain primes are [233,239] or [1369013,1369019] in distance 6.
