• Primes which are a concatenation of n and prime(n).at n=33A084667
• Primes of the form (p^2 + 9)/2 where p is prime.at n=25A347530
• For a line L in the plane, let C(L) denote the number of prime points [k, prime(k)] on L, and let M(L) denote the maximum prime(k) for any of these points. a(n) is the maximum of the smallest primes in the lines L with C(L) = n and containing prime A376187(n), or a(n) = -1 if no such lines exist.at n=39A376190
