OEIS Sequences

Triangle read by rows: T(n,m) (n >= m >= 1) = number of line segments formed by drawing the lines connecting any two of the 2*(m+n) perimeter points of an m X n grid of squares. A331454

a(0) = 0 by convention; for n>0, a(n) is the number of edges in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter). A331448

Terms in A003325 which are sum of two subsequent terms in A003325. A145732

Smallest zeroless number·such that xⁿ has exactly n zero digits. A233821

Number of cells formed by connecting all the 4n points on the perimeter of an n X n square by straight lines; a(0) = 0 by convention. A255011

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph. A367324

Least number starting a chain of exactly n consecutive even integers that do not have cototient-inverses. A72296
