Talk:Figurate numbers

From OeisWiki
Jump to: navigation, search

At first I thought highlighting primes among the centered polygonal numbers might yield some interesting pattern like Ulam's spiral, but so far I haven't noticed anything. If no one else does either, I'll just scrap that idea.

With the formulas, there is a certain style that I prefer, but the main concern should be that the formulas are correct.

As for formatting, I'm pretty much open to anything at this point. Alonso del Arte 23:19, 12 January 2010 (UTC)

Excellent figurate number diagrams


Daniel Forgues has done a phenomenal job with these graphics. The first time I saw them I was like, "Wow!" It would be faint praise to say that these brightly colored dots blow Wikipedia's dull gray dots out of the water, until you consider that they've had years already to work on it. I like these colors a lot better than Mathworld's connecting lines (though to be fair to Mathworld, the colorblind will also get the point—no pun intended).

Look at [1] to see who is the author. I am sure that also Daniel gave reference. Peter Luschny 21:27, 13 August 2010 (UTC)
Sorry about that. Still, Daniel deserves credit for putting them in. And of course Peter Luschny deserves credit for having made these excellent diagrams in the first place. Alonso del Arte 21:59, 13 August 2010 (UTC)
Hi Alonso! I did not made these diagrams. Please read! Peter Luschny 22:26, 13 August 2010 (UTC)
Alright, before I make any further misdirected apologies, who is Stefan Friedrich Birkner and what was his original purpose for these diagrams? Alonso del Arte 22:46, 13 August 2010 (UTC)
When I know that a contribution is from Alonso del Arte and Alonso del Arte wants attribution then I give Alonso del Arte attribution but do not know who Alonso del Arte is and do not know what Alonso del Arte's original purpose for his contribution is. I do not understand your remarks. Peter Luschny 22:59, 13 August 2010 (UTC)
I mean, is Stefan Friedrich Birkner a renowned mathematician or computer programmer, or a number theory aficionado? Were these diagrams originally for his own website, or for Mathworld, or for this website? Alonso del Arte 23:07, 13 August 2010 (UTC)
I do not know and wonder why you think that I should know. Peter Luschny 23:13, 13 August 2010 (UTC)
Since you're the one who uploaded the files, I thought you would have some idea under what circumstances the author allowed us to use it. Was it because you asked him, or did he come to you saying "I think these would be nice for the OEIS?" Alonso del Arte 01:10, 14 August 2010 (UTC)
Oops! I had not put the credits to Stefan Friedrich Birkner on Figurate numbers (now its done), although I had done it on Polygonal numbers and Centered polygonal numbers! Daniel Forgues 23:18, 13 August 2010 (UTC)
