In case anyone wants to discuss the contest for Wolfram's rule 30 on Community, please respond on this thread.

It's about the center column of rule 30. There are three questions. The answer is a mathematical proof. There are cash prizes.

Hi everyone, can anyone tell me if the rule 30 prize is still running? I have been working very hard on it for about a year! I have left a comment on the offical page, which is still awaiting moderation, just getting a bit nervous that everyone has forgotton about it! Thank you, David

(Right) Power spectra of the 4th order co-effecients WOW! really exciting find :-)

Graham this looks neat. Can you explain a little more?

I understand that it's not in Mathematica. If it's one or two lines of math, we can translate it.

It's hard to tell if it's new, Michael. Can you explain here a little more about what you've done?

Usually there will at least be a part of something like this that's new.

Thanks!

Thanks, yes, that sounds familiar from a talk Eric Rowland gave. It is pretty neat though, and yeah, a little hard to explain in words.
