Re: [math-fun] Ulam number picture
OK, let's start again. To all: I have a picture of the Ulam numbers that illustrates their quasiperdiocity. I created this picture a long time ago and sent a copy to Eric Weisstein thinking that he might use it in Mathworld, but apparently no interest. To all, (esp. Hugo Pfoertner, Dan Asimov): I am planning on getting rid of the image. Before doing so, I will send a copy to whomever requests. To NJAS: I will send you a copy, which you may place on your web site if you wish, in association with A002858. The image is actually fairly simplistic, and easily reproducible, and I do not care about attribution. To Daniel Asimov: A PNG is a Portable Network Graphic file. PNG images are fairly common on the Internet and viewable using all major browsers and PC utilities. I prefer PNGs because they are (1) public domain (unlike most other image formats) (2) small (unlike Microsoft BMP or Compuserve GIF images) (3) faithful (unlike JPG images, which sacrifice image quality for small size).

It seems a waste to get rid of, well, anything, in this age of essentially free storage. David, want a gmail account? Then you could send the picture to anyone who wanted it, and a copy of it would be in your record of outgoing mail forever. (Well, there is a 1Gb limit on the size of your stored mail, but your png is a drop in the bucket.) (Gmail accounts used to be rare when the service was in early testing; once-coveted invitations are now easy to get. Ask me if you want one, anybody. The down-side to the service is that your web-based email is decorated with marginal text advertisements (like those that appear after you do a Google search) or other interesting links. I find them unobtrusive and occasionally worthwhile. For example, the link that accompanied David's email was to Eric's Treasure Trove of the Life CA FAQ.) --Michael Kleber -- It is very dark and after 2000. If you continue you are likely to be eaten by a bleen.
No, I think I'll be fine on the email front. I don't have that much worthy of outside storage anyway. This image is basically a piece of junk (albeit interesting junk). ----- Original Message ----- From: "Michael Kleber" <michael.kleber@gmail.com> To: <ham>; "math-fun" <math-fun@mailman.xmission.com> Cc: "Sequence Fans" <seqfan@ext.jussieu.fr> Sent: Monday, February 21, 2005 2:29 PM Subject: Re: [math-fun] Ulam number picture
