• Smallest number of complexity n: smallest number requiring n 1's to build using + and *.at n=37A005520
• Primes p such that 7 is the largest of all prime factors of the numbers between p and the next prime (cf. A052248).at n=25A080186
• Primes of the form 16*k-1 such that 4*k-1 and 8*k-1 are also primes.at n=31A101793
• Primes of the form 7n^2 - 1.at n=8A201793
• Primes of the form (k^3 - k^2 - k - 1)/2 for some integer k > 0.at n=11A268063
• Lesser of twin primes such that the sum of the twin prime pair is the sum of 2 positive cubes.at n=4A270244
