The smallest prime average of seven consecutive primes: 7, 11, 13, 17, 19, 23, 29. [Silva]

Emirp 17 yields three other emirps if 1, 7, and 1+7 zeros are sandwiched between its digits. Obviously, the same can be said of emirp 71. [Silva]

The sum of the digits of first primes up to emirp 17 is the next emirp. [Silva]

If in each of the twin primes 17 and 19 you sandwich the last digit 9, you will obtain a pair of three-digit twin primes (197, 199). [Silva]
