• Primes of the form 7n^2 - 9.at n=19A201854
• a(n) is the least number such that bigomega(a(n)) = bigomega(R(a(n)))/n, where R(n) is the digit reverse of n and bigomega(n) is the number of prime divisors of n counted with multiplicity.at n=11A284496
• Values of abs(P(x)), with P(x) = (1/72)*x^6 + (1/24)*x^5 - (1583/72)*x^4 - (3161/24)*x^3 + (200807/36)*x^2 + (97973/3)*x - 11351, for -45 <= x <= 12, sorted by size. All values in the given range are prime.at n=11A330364
