Beautiful! I was seeing lots of LWSS signatures when I looked at three- and four-block seeds with the SODGame, but couldn't come up with even a four-block clean version. This one is really impressive!knightlife wrote:Well, I didn't expect to find it so soon.

Just had a quick look at other common still lifes that can produce a clean pi explosion when hit by a glider. Ponds, ships, boats, beehives, and blinkers are the ones I know about. Many of them can be trivially substituted in for the block -- just line up the two-cell part with the top of the block, and it will generally work just the same.dvgrn wrote:It's too bad that one of the blocks barely obstructs the alternate glider lane from the NE that could set off the pi-heptomino explosion, to produce a backward LWSS seed. But there are certainly lots of other possibilities for building that pi -- two blocks, or some other still life, instead of the initial target block. (Haven't had time to play around with that yet.)

Probably a little more expensive than three blocks and a little cheaper than three beehives, yes -- but an LWSS may not be quite as useful as an MWSS, anyway, so I think the three-block MWSS seed might win the competition for now.knightlife wrote:This old pattern is easier to construct?

Very nice collection! I recognize a few of the ones I've been using, but most are new to me.codeholic wrote:3-block glider duplicator seeds.
Well, I thought about that, but it would be quite tricky to find this out without modifying gencols' code, because it cannot filter by objects, if the pattern consists of several of them. For finding those G->2G reactions I filtered for asynchronous output with exactly 10 cells, but still I had to filter out G->G+boat manually. With 15 cells there will be much more variants of G+still lifes, I'm afraid.dvgrn wrote:So... are there no G->3G reactions from 3-block constellations, according to gencols?
False positives I generally don't mind so much... as long as it's possible to filter for 15-cell aperiodic patterns, it seems like it should only take half an hour or so to write a Python script to post-filter the gencols output, to flag all the candidate patterns with no still-life component.codeholic wrote:Well, I thought about that, but it would be quite tricky to find this out without modifying gencols' code, because it cannot filter by objects, if the pattern consists of several of them.
