Re: Methuselah based spaceships

Welcome to the forums! PkmnQ didn't necessarily mean that using a helix to make a rake was "overkill", rather they meant that it would not work at all, since more spaceships are being consumed than emitted. However, its speed, (13,1)c/31, is special because one of the B-glider reactions mentioned ea...

Re: Thread for basic non-CGOL questions

A 3c/4 frontend alternates between moving ahead by a full diagonal (due to B1c) and a half diagonal. The only way to move faster is to have 2 full diagonals, but this means that B1c is on in both even and odd generations, meaning that the rule explodes at c. Without B0, we can only move a half diago...

In 2010, Paul Tooke built a similar device, but it uses sqrt-layers, so it only grows at t^3/2. Still, it would be fairly easy to add a slow-enough gun (Simkin's with a few semi-snarks?), write a glider-pair script, and maybe rebuild the whole thing with modern technology to make it smaller and chea...

Re: Vaccinated glider loop challenge

An option to do to it with an unknown period is to make a glider pair delayed by 77 (at 76, the reaction only protrudes a single cell) followed by a large gap (a multiple of 74, so we can fill it in easily). When the gliders return, the MWSS produced will trigger some other stuff, which rebuilds the...

Re: Challenges

It seems to be some sort of error-correcting code on 12 bits (a Hamming code?). The original message can be recovered if there are one or probably even 2 errors (EDIT: the Hamming distance between codewords is 8, so it can correct errors of up to 3 bits and detect 4-bit errors).
