• Sum of squares of the first n primes.at n=36A024450
• Consider the line segment in R^n from the origin to the point v=(2,3,5,7,11,...) with prime coordinates; let d = squared distance to this line from the closest point of Z^n (excluding the endpoints). Sequence gives d times v.v.at n=36A059804
• n = k^2 - (reversal of k)^2 for two different values of k.at n=23A087672
• Numbers which can be expressed as the product of numbers made of only sixs.at n=24A161144
• Sum of the squares of the first A111441(n) primes.at n=2A217600
• Smaller of pairs (m, n), such that the difference of their squares is a cube and the difference of their cubes is a square.at n=16A261296
• Coefficients in q-expansion of (E_2*E_4 - E_6)/720, where E_2, E_4, E_6 are the Eisenstein series shown in A006352, A004009, A013973, respectively.at n=22A281372
