Properties

Appears in sequences

• Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted the two central terms are both 36.at n=6A031624
• Let p(k) = k-th prime; sequence gives primes q of the form q = k*p(k) - 1 for some k.at n=12A096065
• Number of partitions of n into parts but with two kinds of parts of sizes 1 to 7.at n=23A103926
• a(n) is the largest prime that is a sum of some 3 distinct previous terms.at n=24A226027
• Numerators of upper primes-only best approximates (POBAs) to sqrt(3); see Comments.at n=18A265780
• Numerators of primes-only best approximates (POBAs) to sqrt(3); see Comments.at n=9A265782
• Smallest primes of 4 X 4 semimagic squares formed from consecutive primes.at n=42A270865
• Primes p such that phi(phi(p-1)+1) = phi(phi(p-2)+1).at n=21A271659
