Actually it's a 20-bit still life.

Each of the blocks can be replaced by a glider, giving a 10-glider synthesis:

Code: Select all

Courtesy Catagolue: 10-glider synthesis for 14.352, previously from 15 gliders - for almost two decades, the last remaining still-life up to 14 bits that could not be synthesized for <= 1 glider/bit. This yields trivial 12-glider syntheses for the related boat versions 15.615 and 15.618, beehive version 16.1314, barge versions 16.1312 and 16.1320, and loaf versions 17.2052 and 17.2063:

I specifically listed the 2 15-bit ones, because I already had syntheses for those, and I'm specifically tracking all the 15-bit ones. I only included the larger ones because those were trivial to make with 2 extra gliders. I know a 2-glider tub-to-bun converter, but the 2-glider tub-to-mango and 3-glider tub-to-bookend converters are new to me. Thanks!

### Re: Syntheses of Unusual Still Lifes

A 16-bit still-life (moose antlers with one eater head replaced by a tub) showed up in a random soup that I was running, formed by adding a blinker to a common predecessor of moose antlers. Using 4 gliders to build moose antlers gives this 6-glider synthesis:

Code: Select all

``````x = 24, y = 16, rule = B3/S23
9bo\$10b2o\$9b2o\$20bo\$20bobo\$4bo15b2o\$2bobo\$3b2o3\$3o\$2bo\$bo6b3o\$10bo10b
3o\$9bo11bo\$22bo!``````
I don't see this object in Mark Niemiec's list of still-lifes buildable from 6 gliders (or fewer), so maybe this is an improvement.

But the same mechanism occurs in some random soups in the Catagolue, so I wouldn't be surprised if it's been found before.

This is 16.1452, and it has no explicit synthesis yet in my own internal database (it implicitly takes 7 - 4 for antlers + 3 for eater head-to-tub), although I haven't yet had a chance to examine all of Bob Shemyakin's small syntheses to see if any of those include this object. He might be able to answer that.

### Re: Syntheses of Unusual Still Lifes

Mark Niemiec's database gives a 14-glider synthesis of the 16-bit still life "teardrop tie loaf". Here's one with 12 gliders:

Code: Select all

``````x = 105, y = 80, rule = B3/S23

This showed up in a 5-glider collision, forming in generation 1958, but with so much extra junk that cleaning it up with fewer than 7 more gliders seems difficult:

Code: Select all

``````x = 37, y = 32, rule = B3/S23

Meanwhile, I found a 7-glider synthesis, based on one of the 1144 soups in the Catagolue that produces this object:

Excellent!
Thanks. From now on I'll compare any of my 'improved' syntheses to yours in that thread. Are there any other synthesis collections that I should know about?

By the way, I see that many of the RLE files in 5gliders.rar have bad headers, like "x = -78, y = -60, rule = S S23/B3" in p2o8g5-bipole.lif. Golly ignores the negative x and y values, but interprets the rule as one in which every cell dies, so I've edited my copies to correct that. I've seen this rule error before; do you know what causes it?

The pattern must have been saved in Life32. Version 2.16 was the only one that did that, if I recall correctly. EDIT: I recognize both the negative dimensions and the extra S in "S S23/B3". Very strange bug -- it only happened sometimes. But Golly came along, and then a new patched version of Life32 never surfaced.

Or WinLife32. I use v2.2.0 (preferred for its drag and drop sensibility). I haven't noticed the negative dimensions, but always have to open the RLE in a word processor to swap the S23/B3 to B3/S23 before posting up the patterns.
Golly doesn't seem to mind the reversal though.

This seems to be new; both Mark's site and Bob Shemyakin's files give 7-glider syntheses of this.
Very nice! My synthesis would now actually take 6, since it was based on 12.28 (block on down long bookend) + 2
gliders for eater-head-to-down-boat, but Bob Shemyakin had recently (within the past couple of years) reduced 12.28 to 4 gliders. Unfortunately, that one synthesis forms the basis for literally hundreds of others, so I haven't yet had the time to update everything it affects yet.

### Re: Syntheses of Unusual Still Lifes

A bit awkward two-sided synthesis of a 21-cell SL:

Code: Select all

``````x = 105, y = 57, rule = B3/S23

And a probably improvable 17-glider synth of a 19-bit SL:

Replacing 2 of the gliders that form a blinker by 2 that form a blinker and a loaf gets rid of the escaping glider, so this uses 16 gliders:

I specifically listed the 2 15-bit ones, because I already had syntheses for those, and I'm specifically tracking all the 15-bit ones. I only included the larger ones because those were trivial to make with 2 extra gliders. I know a 2-glider tub-to-bun converter, but the 2-glider tub-to-mango and 3-glider tub-to-bookend converters are new to me. Thanks!
