• Sum of squares of the first n primes.at n=29A024450
• 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=29A059804
• a(n) = n*(n+1)*(n^2+1)/2.at n=22A071237
• Numerator of the contraharmonic mean of the first n primes.at n=29A296199
