## B026/S1

For discussion of other cellular automata.

### B026/S1

B026/S1 is an explosive rule uncovered by Extrementhusiast and further explored by lots of other people. The two basic spaceships are two c/2 p4 diagonals:
`x = 13, y = 4, rule = B026/S18bo2\$3bo4bo3bo\$obo8bo!`

As well as a p8 variant:
`x = 8, y = 8, rule = B026/S17bo\$6bo2\$6bo2\$bobo\$o\$6bo!`

There's also a replicator that travels at the same speed, but period 16:
`x = 2, y = 2, rule = B026/S1bo\$o!`

Replicators can be combined to achieve lower periods:
`x = 28, y = 29, rule = B026/S1o\$bo2\$3bo\$4bo7\$11bo\$12bo3\$15bo\$16bo7\$23bo\$24bo3\$26bo\$27bo!`

p16 double rake along with a reflection reaction:
`x = 5, y = 39, rule = B026/S13bo\$obo31\$bo5\$4bo\$3bo!`

p68 quad rake:
`x = 7, y = 5, rule = B026/S16bo\$bo3bo\$o\$3bo\$obo!`

A puffer:
`x = 7, y = 12, rule = B026/S1o4\$b2o2\$6bo\$3bobo\$bo2\$bo\$o!`

There's also this arbitrarily large period spaceship:
`x = 48, y = 36, rule = B026/S115bo\$14bo2\$12bo\$11bo7\$4bo\$3bo2\$bo\$o12\$20bo\$19bo2\$19bo2\$47bo\$46bo2\$46bo!`

5-cell breeder:
`x = 9, y = 5, rule = B026/S18bo\$7bo2\$3bo\$obo!`

p2 and p16:
`x = 36, y = 3, rule = B026/S1o6bo5bo5b3o7bo2bo2bo\$5bo6b3o4b3o\$13bo5b3o!`

Rake-type thing:
`x = 17, y = 14, rule = B026/S1o8\$12bo\$11bo\$14bo\$13bo\$16bo\$15bo!`

Extrementhusiast found a gun:
`x = 29, y = 13, rule = B026/S1bo\$2bo25bo\$27bo8\$bo\$o25bo\$27bo!`

There has also been interest in 1-cell thick soups, which do not explode. They cannot explode because they are bound to move only on one axis, and do not move much on that axis. However, this movement can support spaceships! Two have occurred naturally, 2c/10 and 2c/24:
`x = 35, y = 6, rule = B026/S1obo2b5o3b7o5\$7o2bobo2b3o2bo2bo3b3o2bo2bo!`

Unnaturally, there are 2c/8, 2c/12, 2c/14, and 2c/16 spaceships:
`x = 614, y = 16, rule = B026/S1o3b3o3bo2bobo2bo3bo2b11o2bo2b3o4b2o5\$o3b3o3bo2bo2bo2bo2b3o3b7o2bobo2b3o2bo2bo2bo2bo4b7o3bo3bo3b5o2bobo2bo3b5o2bobobobo2b5o3b6o3b5o3bo2bobobobo2bo3b6o2bobo2bo4bo2bobobo2bo2bobobobo2bo3bo2bobobo2b3o2bobobo2b3o3b3o3b3o2bo2bo3bo3b3o3bo3bo3b3o2bobobo2bo2bobobo2bo3bo3b3o3b3o3bo2bo2bo3bo2bo2bo2bo2bo2b10o3b3o2bobo2b2o2bobobo2b3o2bo2bo3b3o3bo3bo2bobo2b11o3b5o2bo2b15o2bo2b7o3b5o2bobobobobobobo2bo2bo3b3o3b5o2bobo2bo2bobobo2b5o3b3o2bobo2bo2bo2b6o2bo2bo2bo2bo3b3o2bobobo2b6o3b7o3b7o2bobobobo2b3o3bo2bobobo2b2o5\$o3b3o3bo2bo2bo3b7o3b5o2bobo2bo3bo2bo2bo3b2o2bobobo2b3o2bo2b3o3bo2bo2bo2bo3bo2bobo2bo3b3o3b2o3bo3b7o3b3o2bo2b9o2bobo2bo3bo3b5o3bo2bobobo2bo2bobo2bo2bo2b3o3b3o3b3o2bobo2b11o2bo2bo2bo2b3o2bo2b3o2bo2bo3b3o2bobo2b3o3b5o2bobobobobobobobo2b5o3b5o2bo2bo2bo2b3o2bobo2bo3b3o3b3o3b5o3b5o2bo2b7o3bo2bo2bo2bo2b3o3b5o2bo2b11o3b3o2bo2b5o3bo5\$2o3b3o2bobobobo2bo2bo2bo3b7o3b7o2bo2b7o3bo3bo2bo!`

There's also a tagalong for the 2c/10:
`x = 16, y = 23, rule = B026/S111bo3bo4\$o12bo\$o12bo\$o12bo3\$o12bo3\$o12bo4\$o12bo3\$o12bo3\$o12bo!`

All of this and more can be found here, I reiterated some of the discoveries but please do consider reading through.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night

Single-replicator version of Extrementhusiast's p32 gun:
`x = 24, y = 24, rule = B026/S122bo\$21b3o\$22bo3\$9bo5bo3\$18bo2\$12bo\$13bo8\$o4\$4bo!`
Iteration of sigma(n)+tau(n)-n [sigma(n)+tau(n)-n : OEIS A163163] (e.g. 16,20,28,34,24,44,46,30,50,49,11,3,3, ...) :
965808 is period 336 (max = 207085118608).

### Re: B026/S1

Infinitely extensible one-dimensional 2c/10 tagalong:
`x = 69, y = 15, rule = B026/S13o2bo2bo3bo2bo2bo3bo3bo3b3o3bo2bo2b5o2bobo2b5o3b7o7\$26bo3b3o3bo2bo2b5o2bobo2b5o3b7o7\$49bobo2b5o3b7o!`

I'm still surprised that the 2c/10, 2c/24 and tagalong 2c/10 are the only natural spaceships so far found in 1x256 - one would think some from the 2c/8, 2c/16 and 2c/18 would have turned up by now, since they're not that long or complex.

A new natural 4c/20:

Only just slightly smaller than the currently undiscovered 2c/8 as well, so here's hoping that comes up soon.

Can't seem to find a clean 90 degree turn reaction.

Hence why I search it on 1x256.

Wait, you can search bounded grids?

No, it's just that one can apgsearch 1D soups (since this rule in 1D emulates a 1D next-nearest-neighbors rule which is not explosive)
Please, stop spam searching Snowflakes.
