Re: 15 in 15: Efficient 15-bit Synthesis Project (DONE!)

... I did quite a bit of work on making syntheses for all 16-bit still lifes. Adding many of the converters from Extrementhusiast's list and then making more expensive versions that have smaller reaction envelopes to get a few of the harder cases. There are still around 200 still lifes without a sy...

Re: 4 glider syntheses

See the 4-th still life in the 8-th row Bob Shemyakin My point is that the synthesis is invalid. The top two gliders already react at generation "-1". Advance the left hand side by 1 generation and you do not get the right hand side: x = 25, y = 19, rule = B3/S23 2bo20bo$2bobo16b2o$2b2o18b2o2$2bo$3...
