New file / Ulam spirale.
- Well, it is a nearly new file, it is the final version of my book about the Ulam spiral and similar primepatterns.
You can find it under visuliazations, called "Primepatterns".
I think I kick the Ulam spiral, there is allso some material about
n^2-n+p, and the book should be the first choice, if anybody ask about patterns.
If no one come with serious negative comments, then I will go on to argue about it at Wikipedia.
