OEIS Sequences

Number of partitions p of n such that (number of numbers in p of form 3k+2) < (number of numbers in p of form 3k). A241740

T(n,k)=Number of nXk 0..1 arrays with every element unequal to 0, 1, 2 or 3 horizontally, vertically or antidiagonally adjacent elements, with upper left element zero. A318016

E.g.f. A(x) satisfies: (A(x)⁵ - 10·x)² = (2 - A(x)²)⁵. A249787

Place n equally spaced points on the circumference of a circle of radius r and then connect each pair of points with straight lines whose intersections create A007569(n) - n additional points. Draw a circle of radius r around each of the A007569(n) points. The sequence gives the total number of regions formed from all circle intersections. A374826

a(n) = Fibonacci(n+6) - Fibonacci(6). A180671
