Re: Pattern viewer for forum threads

If I run the pattern in this post with increased step size, LifeViewer gives a wrong answer about when the life ended.

Re: New still life

Hello, and welcome to the forums! Unfortunately, new still lifes are generally very boring, to the extent that even the official rules mention them as an example of uninteresting patterns. The reason behind it is very simple: still lifes are too easy to find and there are too many of them. If I want...

In your case, the best thing to do is to put a line break before this expression, which will give a 69-char line. Having lines that a...

What you are describing seems like a parabolic sawtooth . Edit: Some details are different, but I think the main scheme and e.f. being arbitrarily close to 1 looked the same. My design is of course heavily based on parabolic sawtooth. However, the expansion factor of parabolic sawtooth is equal to ...
