• Let v = (1,4,9,...,n^2), x = (0,1,2,4,6,...) [first n terms of A002620]; a(n) = v.v * x.x - (v.x)^2.at n=12A060452
• Consider the line segment in R^n from the origin to the point v = (1,4,9,...,n^2); 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=11A060454
• a(n) = Pell(n)^3 + Pell(n+1)^3.at n=4A110273
• <h[d,d],s[d,d]*s[d,d]*s[d,d]> where h[d,d] is a homogeneous symmetric function, s[d,d] is a Schur function indexed by two parts, * represents the Kronecker product and <, > is the standard scalar product on symmetric functions.at n=39A115375
• Numbers of the form 49*k, where 49*k+2 and 49*k-6 are both prime.at n=10A153779
• Numbers 41*k such that 41*k+2 and 41*k-6 are both prime.at n=8A153822
• Number of (w,x,y,z) with all terms in {1,...,n} and w*x < 2*y*z.at n=14A211795
• Triangle read by rows: T(n,k) (0 <= k <= n) = numerator of Integral_{x=0..n} binomial(x,k).at n=32A241186
• Total number of parts in all partitions of n with designated summands.at n=18A388064
