Re: One Glider Seeds

Am I accidentally sending (potentially annoying) notifications when I edit the information back in, and if so, is there an alternative that doesn't send unnecessary notifications? Edit notifications might happen occasionally, but if so I haven't noticed them. Probably no need to worry about them. I...

Re: One Glider Seeds

The Python3 find-octohash script turns out to be a good tool for this kind of thing. it found a hundred and seventy-odd clean Herschel descendant seeds, and I only had to look as far as the eighth constellation to find one that allowed a glider to sneak in from outside… Why did I get a quote notifi...

Yeah, I checked in a Python3 version here a couple of weeks ago, for wildmyron's improved version of the database (duplicates removed, and a subset of 4G collisions added).

The R-pentomino doesn't have to be formed that way. I tend to include the original reaction that I found the reaction in, but should I stop doing that? No need to stop, but maybe make it a little more parenthetical? "(originally found in this reaction at T=227): [ RLE ]". This one had a particular ...

Re: Thread for basic questions

That being said, if you place your blinkers and pre-blocks very carefully, you can get really-long-lived methuselahs with less cells than that. True... except I still would be very careful not to call those "methuselahs", because at this pattern size, there are still probably more of them than ther...

Re: Thread for basic questions

is this considered a methuselah? Not really. There are probably more different Life patterns of that size that last longer than 36,000 ticks, than there are electrons in the observable universe. A methuselah generally starts with a much smaller bounding box and population than that; otherwise you c...

Is that not 15G, instead of 16G? The glider and pattern shown in the middle step is duplicated in the last step, and the initial blinker comes from 2G. Yup, I did the layout wrong -- should have been x = 236, y = 81, rule = B3/S23 214bobo$214b2o$215bo$124b2o78b2o$123bo2bo4bo71bo2bo4bo$123b2obo3bobo...

Re: Soup-searching for potentially conduit-yielding reactions

Observe the interaction in the upper-right starting at generation 227... At T=227 you have an R-pentomino heading leftward, and the fishhook turns it into a century, but the century shows up in the middle of a bunch of already-used territory from T=140 to T=160 or so. Why would a century be useful ...
