+ The first of a dozen consecutive primes that remain primes if you delete each first digit. [Loungrides]

+ The start of a dozen of consecutive primes, i.e., {607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673}, such that deleting their first digit, we find another set of a dozen distinct primes, i.e., {7, 13, 17, 19, 31, 41, 43, 47, 53, 59, 61, 73}. It is the largest known sequence of primes with this property. [Loungrides]
