OEIS Sequences

Sum of squares of the first n primes. A24450

Consider the line segment in Rⁿ 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 Zⁿ (excluding the endpoints). Sequence gives d times v.v. A59804

Numerator of Sum[ Prime[k]², {k,1,n}] / Product[ Prime[k], {k,1,n}] = Numerator[ A024450[n] / A002110[n] ]. A122136

Numerator of the contraharmonic mean of the first n primes. A296199

Number of primitive (aperiodic) step shifted (decimated) sequences using exactly three different symbols. A56387
