Hello Robert,
I have proposed a change to the De Bruijn's triangle (draft).
It doesn't look great, but this array clearly has a row(0)=1,1,1... and row(1)=1,1,1..., just like all the columns have a(0)=1 and a(1)=1.
Also the lower triangle A141906 starts with row 0, and the transpose A089759 has a column 0.
I also added a significantly larger b-file, showing the first 54 triangle rows.
BTW, could you give a source for the term De Bruijn's triangle? Greetings, Tilman Piesk 14:28, 29 October 2014 (UTC)

Does this version look ok to you? If you agree to my changes, just say so in the comments. If not I will modify my edits. Tilman Piesk 14:25, 30 October 2014 (UTC)

a sequence similar to A280594 while include 15 or 1590

Dear Robert,

Nice to meet you and thank you for your praise. Okay! It is a nice sequence to be submitted. (I am a bit tired becoz of other issues, and the extending or maintaining of the "keypad sequences" are not my focus temporarily...)

Hi, I used your factorizations in A038507/a038507.txt for draft/A333058 and found a typo at primorial(14) - 1, "141369 * 92608862041" should be "141269 * 92608862041". –Frank Ellermann (talk) 03:43, 17 March 2020 (EDT)
