Properties

Appears in sequences

• a(n) = T(n,m) + T(n,m+1) + ... + T(n,n), where m = floor((n+2)/2), T given by A027948.at n=15A027958
• 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 17.at n=31A031605
• Let p(k) denote k-th prime; consider solutions (p(n),p(m)) of Diophantine equation p(p(n)+1)-6.p(p(m))=1 (*), where p(p(n)) belongs to A060213 and p(p(m))=(p(p(n))+1)/6; sequence gives values of p(n).at n=8A065505
• Primes of the form 3n^2 + 10.at n=23A201480
• Primes of the form 2*n^2 + 46*n + 21.at n=18A217495
• Number of partitions p of n such that (number of distinct parts of p) <= max(p) - min(p).at n=43A239955
• Prime numbersat n=6173
