• Bemirps: primes that yield a different prime when turned upside down with reversals of both being two more different primes.at n=11A048895
• Primes of the form pq - 6, where p and q are consecutive primes.at n=28A099775
• Primes of the form prime(x)*prime(x+1) - (prime(x+1)-prime(x)).at n=14A140120
• a(n) is the largest n-digit bemirp (A048895).at n=2A177137
• Bemirps that also interpret 2 and 5 as upside-down forms of each other, assuming a digital font.at n=23A335731
• Emirps p such that p+(sum of digits of p) and reverse(p)+(sum of digits of p) are emirps.at n=18A340843
• Primes p such that if q is the next prime, the sum (with multiplicity) of prime factors of p^2 + q^2 is a square.at n=38A359443
