Primes formed by concatenating n with n+1. A30458
Primes whose decimal expansion is a concatenation of two or more consecutive increasing numbers (no leading zeros allowed). A52087
Irregular triangle where row n lists primes q below the n-th primorial such that the multiplicative order of q mod the n-th primorial is 2. I.e., such primes q having the least k such that qk (mod primorial(n)) == 1 is 2. A336015
Primes p such that d(p2-1) sets a record, where d(n) is the number of divisors of n. A335325
