COMMENTS

Suggested (without definition) by A. Groeneveld in reply to a question on the SeqFan list.

The "limiting row" is given by A232089.

The diagonal T(i, i) also tends to A232089. - Michel Marcus, Dec 22 2014

LINKS

Table of n, a(n) for n=0..91.

A. Groeneveld, Re: guess the relation, SeqFan mailing list, Jan. 2014.

EXAMPLE

The table goes like:

(row n=0) 1

(row n=1) 1, 1

(row n=2) 1, 1, 1, 2

(row n=3) 1, 1, 1, 1, 1, 2, 4

(row n=4) 1, 1, 1, 1, 1, 2, 1, 1, 2, 4, 8

(row n=5) 1, 1, 1, 1, 1, 2, 1, 1, 2, 4, 1, 1, 2, 4, 8, 16

PROG

(PARI) list_A232088(nRows, a=[1])=for(i=1, nRows, print(a); a[#a]=vector(i+1, j, max(2^(j-2), 1)); a=concat(a)); a

CROSSREFS

Row lengths are A000124(n)=n(n+1)/2+1.
