• Primes p such that p's set of distinct digits is {1,3,7,9}.at n=28A108386
• Let a(1) = least prime p such that 18517# + p is = q(1) prime, then a(n+1) = least number such that q(n)*(q(n)+a(n+1))-1 is prime.at n=0A144306
• Primes of the form k^3 + 13, k >= 0.at n=4A176722
• Number of lower triangles of an n X n 0..3 array with new values introduced in row major order 0..3 and no element equal to more than two horizontal or vertical neighbors.at n=3A194571
• T(n,k)=Number of lower triangles of an n X n 0..k array with new values introduced in row major order 0..k and no element equal to more than two horizontal or vertical neighbors.at n=18A194576
• Primes congruent to 5 (mod 504).at n=28A228093
