Re: script for puffer producing given output

I haven't seen anyone else asking a question like this, so there doesn't seem to be much call for such a program or script. If this is an one-off then it would be easier to produce the pattern by hand. I have constructed such a puffer and include it in a reply to the original request in the patterns...

Re: Cheap way to construct a c/2 p168 puffer

I don't know whether this is the cheapest or most compact solution, but it works. It uses fourteen p168 forward rakes and incorporates the LWSS-catalysed forward glider->block reaction suggested by Jason Summers replying to the related topic in the scripts forum . Presumably you have an interesting ...

Re: Firing squad synchronization problem

An interesting challenge! Here's a simulation of Mazoyer's 6-state solution. The .zip file contains a width 243 starting pattern and the .table and colors file. To view this pattern, simply open the .zip file in Golly and run it. If you extract the .table and .colors files to your Golly Rules folder...

Re: List of C/4 puffers & rakes?

Take a look in Jason Summers' pattern collection, downloadable from http://entropymine.com/jason/life/ . You won't find a lot of them I'm afraid. To the best of my knowledge, the only c/4 puffer engines in existence are a p28 c/4 diagonal puffer found by Hartmut Holzwart and a p168 orthogonal puffer...

Re: New c/3 puffer

Nice one! Thanks also to Sokwe for the rake. Throwing rubbish into the puffer exhaust can create a p18 spaceship or p72 puffer. Examples of both of these types already exist, but as far as I know each these are new. Perhaps a use could be found for them. x = 80, y = 58, rule = B3/S23 6b2o17b2o25b3o1...

Re: Life 1.05 to RLE - Help!

There is an easy fix that doesn't require unnecessary programming. Convert it to 'correct' Life 1.05 format by putting this line at the start of the file: #Life 1.05 Golly seems perfectly happy with the pattern posted above when this line is present. It does do something strange though: it retains t...
