• a(n) = 225*(n-1)*(n-2)/2.at n=34A027470
• Consider all integer triples (i,j,k), j >= k > 0, with binomial(i+2,3) = j^3 + k^3, ordered by increasing i; sequence gives i values.at n=24A054205
• Triangle, read by rows, that equals the matrix inverse of A071207 when treated as a lower triangular matrix.at n=50A089962
• Minimal Goedel number of endofunctions on k points, by row and sorted within rows (number of points).at n=28A125024
• A certain partition array in Abramowitz-Stegun order (A-St order), called M_3(5).at n=35A134273
• a(1)=2. a(n) = the smallest positive multiple of a(n-1) that is > a(n-1) and has the same number of 0's as 1's in its binary representation.at n=6A143147
• Number of (w,x,y,z) with all terms in {1,...,n} and w<2x and y>2z.at n=30A212504
• a(n) = lcm(A260443(n), A260443(1+n)).at n=21A284008
• Triangle read by rows. T(n, k) = Bell(k)*Sum_{j=0..k}(-1)^(k+j)*binomial(n, n-k+j)*Stirling2(n-k+j, j) for n >= 0 and 0 <= k <= floor(n/2).at n=34A352607
