OEIS Sequences

Smallest magic constant for any n X n magic square made from consecutive primes, or 0 if no such magic square exists. A73520

A051838 gives numbers m such that the sum of first m primes divides the product of the first m primes. This sequence gives corresponding values of the sum of first m primes. A140763

T(n,k)=Number of length n+k+2 0..k arrays with every value 0..k appearing at least once in every consecutive k+3 elements, and new values 0..k introduced in order. A242322

Primitive values n such that the square with opposite corners (0,0) and (n,n) contains a point (x,y) with integer coordinates, with 0 < x,y < n, at an integer distance from three of the four corners. A260549

Numbers in A007504 such that ω(a(n)) = ω(a(n)) = 3. A264885

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-1)², where a(0) = 2, a(1) = 3, b(0) = 1, b(1) = 4, and (a(n)) and (b(n)) are increasing complementary sequences. A296254

a(n) = floor(Li(2ⁿ)), where Li(x) is the integral from 0 to·of dt/log(t). A89897
