Re: Randomly enumerating glider syntheses

I've committed the new SL syntheses as of 19 January 2020 19:11 UTC+8 to Shinjuku.

Re: cellular automata according to Max Planck

It doesn't need Einsteins theory of relativity to imagine yourself riding along with the glider. You have already lost. I am still searching piece 3. On cellular automata and the real world, Konrad Zuse did write a 1969 treatise called Calculating Space ( Rechnender Raum ) where a model of the phys...

Here's another problem:

21p3.86 xp3_0q52z122qbgzy256

It's a 20P3.

I'm not. 38P7.2 is much easier to synthesise than 37P7.1, so I chose that. For the purposes of Shinjuku only the period matters.

True; however, all P2 (and P3) oscillators up to 21 bits have been enumerated by computer search.

Re: Soup-based syntheses

There's something sinister about bi-pentadecathlon 1. The great majority of them form from a traffic light colliding with a well-developed pi mushroom, and then some kind of spark is applied at the back. Could this be marshalled to give a synth cheaper than 8 gliders?
