OEIS Sequences

G.f.: ∑k>=0 (1 + k·x)k * xk. A360592
Beginning with 3, least prime such that concatenation of first n terms and its digit reversal both are primes. A113584
Sum of the seventh largest parts in the partitions of n into 10 parts. A326592
Locations of the increasing peak values of the integral of the absolute value of the Riemann ζ function between successive zeros on the critical line. This can also be defined in terms of the Z function; if t and s are successive zeros of a renormalized Z function, z(x) = Z(2 π x/log(2)), then take the integral between t and s of |z(x)|. For each successively higher value of this integral, the corresponding term of the integer sequence is r = (t+s)/2 rounded to the nearest integer. A117538
Beginnings of maximal chains of primes with three members (two links). A152866
Nearest integer to locations of increasingly large peaks of abs(ζ(0.5 + i·2*(π/log(2))*t)) for increasing real t. A117536
Primes p such that p1 = ceiling(p/2) + p is prime and p2 = floor(p1/2) + p1 is prime. A158714
Number of partitions of n such that the number of even parts is a part and the number of odd parts is not a part. A240577
Numerators of lower primes-only best approximates (POBAs) to sqrt(8); see Comments. A265790
Primes congruent to 34 mod 45. A142330
