A268318 Irregular triangle read by rows: T(n,k) gives the row sums in the table Fib(n+1) X Fib(n), where k = 1..Fib(n+1), and 1's are assigned to cells on the longest diagonal path.

Comments

Inspired by sun flower spirals which come in Fib(i) and Fib(i+1) numbers in opposite directions. The present Fib(n+1) X Fib(n) table has the following properties:

(i) Columns sum create the irregular triangle A268317.

(ii) Rows sum create the present irregular triangle.

(iii) The row sums of each of these irregular triangles is conjectured to be A000071.

(iv) The first differences of the sequence of half of the voids (0's) are conjectured to give A191797.
