Appears in sequences

• Consider all integer triples (i,j,k), j >= k > 0, with i^3 = binomial(j+2,3) + binomial(k+2,3), ordered by increasing i; sequence gives i values.at n=24A054208
• Expansion of Product_{k>=1} ((1 + x^k)/(1 - x^k))^(sigma_2(k)).at n=10A301556
• Triangle read by rows: T(n,k) is the number of permutations of k elements from [1..n] where adjacent values cannot be consecutive modulo n.at n=62A338838
• a(n) = coefficient of x^n in A(x) such that: 1 = Sum_{n=-oo..+oo} x^n * (A(x) - x^(3*n+2))^(n-1).at n=8A358962
