OEIS Sequences

Place a point on the integer coordinates, up to |n|, along all four axial directions on a Cartesian plane, and then join an infinite straight line between every pair of points: a(n) is the number of points where lines intersect in the resulting graph. A386559

Triangular array, read by rows: T(n,k) = [(x·y)^k] (-1 + (1 + x + 1/x)*(1 + y + 1/y))ⁿ for -n <= k <= n. A329816

Decimal part of cube root of a(n) starts with 1: first term of runs. A34127

a(n) = n*(n+1)*(15·n²-n-8)/12. A172047
