OEIS Sequences

Total number of edges formed after n points have been placed in general position on each edge of a triangle (as in A365929). A366932

Zeroless numbers n whose digit product squared is equal to the digit product of n². A256115

Odd numbers n such that q(n)² = q(n²) ≠ 0, where q(n) is the digit product on base 10. A278316

Array read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the k·n boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph. A392282

Starting positions of strings of three 7's in the decimal expansion of π. A83631

Consider the sequence A235598. Recalling that A235598(n) forms part of a Pythagorean triple, a(n) states its relationship to both a(n-1) and a(n+1). 1 denotes the lesser leg, 2 denotes the greater leg and 3 denotes the hypotenuse. The tens place returns its relationship to the side to its left, a(n-1), and the units place its relationship to the side to its right, a(n+1). a(0)=1. A239431
