• a(1)=1, a(n) is the smallest integer > a(n-1) such that the largest element in the simple continued fraction for S(n)=1/a(1)+1/a(2)+...+1/a(n) equals prime(n).at n=37A070901
• Lengths of prefixes of the infinite string of digits repeat(1379) that are prime.at n=12A247025
• Numbers n such that 36n+11, 36(n+1)+11, 36(n+2)+11 and 36(n+3)+11 are prime.at n=25A255608
• a(n) = number of primes that end in 7 among the first 10^n primes.at n=4A300399
• Trajectory of n under the Reverse and Add! operation carried out in base 8 (presumably) does not reach a palindrome and (presumably) does not join the trajectory of any term m < n.at n=32A306596
