OEIS Sequences

Total number of line segments between points visible to each other in a square n X n lattice. A141255

Shifts 6 places left under inverse binomial transform. A10747

Construct sequences P,Q,R by the rules: Q = first differences of P, R = second differences of P, P starts with 1,3,9, Q starts with 2,6, R starts with 4; at each stage the smallest number not yet present in P,Q,R is appended to R. Sequence gives P. A225385
