Michael De Vlieger, Table of n, a(n) for n = 1..5587
EXAMPLE
Relation of A347354 and irregular triangle A347285, placing "." after the last term in the current row where T(n,k) exceeds T(n-1,k). Since the rows of A347285 reach a fixed point of 0, we interpret T(n,k) for vacant T(n-1,k) as exceeding same. The indices n that are highlighted with parentheses are the terms in this sequence.
