OEIS Sequences

T(n,k)=Number of nXk arrays of the minimum value of corresponding elements and their horizontal or vertical neighbors in a random, but sorted with lexicographically nondecreasing rows and nonincreasing columns, 0..2 nXk array. A219595
Numbers n for which there are exactly five k such that n = k + (product of nonzero digits of k). A96926
a(n) = sum of the first n lower twin primes. A86167
Numerator of (1+σ(s)) / ((s+1)/2), where s is the square of n prime-shifted once (s = A003961(n)2 = A003961(n2)). A337338
Number of lattice points in the closed region bounded by the graphs of y = (5/6)*x2, x = n, and y = 0, excluding points on the x-axis. A227347
Starting from a(1)=1, a(n) is the minimum integer greater than a(n-1) such that a(n)+a(n-1), a(n)*a(n-1)+1 and a(n)*a(n-1)-1 are all primes. A228590
a(n) = floor(τ*a(n-1)) + floor(τ*a(n-2)) with a(0)=1 and a(1)=3. A5913
Numbers k such that A001414(k) is a square and sets a new record for squares. A64463
Number of base 26 circular n-digit numbers with adjacent digits differing by 1 or less. A124719
Sequence defined by the recurrence formula a(n+1)=sum(a(p)*a(n-p)+k,p=0..n)+l for n>=1, with here a(0)=1, a(1)=7, k=0 and l=-2. A177169
