## Whichlife (B2in3aeijn/S234e)

For discussion of other cellular automata.

### Re: Whichlife (B2in3aeijn/S234e)

Oops!

Anyway, I realized that generation 38 of teardrop is this:
`x = 9, y = 9, rule = B2in3aeijn/S234e2o\$obo\$2bo\$2bobo\$b2o2bo2\$4b4o\$4bo3bo\$7b2o!`

There's a low chance that this could possibly be manipulated... somehow...
EDIT: Oops, I forgot that this rule had B2n so it wouldn't work anyway
Life is hard. Deal with it.
My favorite oscillator of all time:
`x = 7, y = 5, rule = B3/S2-i3-y4i4b3o\$6bo\$o3b3o\$2o\$bo!`

Catalysis
`x = 4, y = 10, rule = B2in3aeijn/S234eb2o\$obo\$bo4\$b2o\$bobo\$bobo\$2b2o!`

I’m rather surprised that in two full pages nobody has posted this potentially useful G+B reaction producing a "strange" pseudoSL.
`x = 1, y = 13, rule = B2in3aeijn/S234e9b2o\$9b2o9\$3o\$2bo\$bo!`

I’ve seen this reaction many times and didn’t realize it could be useful until now.

For one thing, it has a 3G synth.
There is a 2-boat pseudoSL that thus has a 4G synth:
`x = 16, y = 16, rule = B2in3aeijn/S234e13b2o\$13bobo\$14bo\$12bo\$11bobo\$11bobo\$12bo7\$3o\$2bo\$bo!`

The BH-B[oa]T PseudoSL is a 1TT (sorry about the abbreviations, I know they’re getting irritating):
`x = 15, y = 15, rule = B2in3aeijn/S234ebo\$2bo\$3o6\$12b2o\$12bobo\$13bo\$11bo\$10bobo\$10bobo\$11bo!`

It also can be struck to produce a temporary XWSS frontend, but is much cleaner (and I believe cheaper) than a B:
`x = 15, y = 25, rule = B2in3aeijn/S234ebo\$2bo\$3o16\$12b2o\$12bobo\$13bo\$11bo\$10bobo\$10bobo\$11bo!#c [[ ZOOM 7 ]]`

It thus may (or may not) provide a reduction to the price of the largest natural SL.

I think you mean a 1TT (one-time turner).

Bump
Can anyone search for a smaller c/3 using this object to stabilize one end?
`x = 3, y = 3, rule = B2in3aeijn/S234e2o\$2o\$2bo!`

I imagine it wouldn’t take long; I found these near misses (2 cells and 1 cell off respectively) by hand and a couple life patterns (and not even the latter for the 2-cell off one).
`x = 21, y = 5, rule = B2in3aeijn/S234e3b2o13b2o\$2ob2o10b2ob2o\$2o3bo6b4o4bo\$2o9bo4bo\$12b2o!`

Here's a longer partial from LLS - it's not looking very likely that there's a reasonably small solution.
`x = 17, y = 10, rule = B2in3aeijn/S234eo13b2o\$obo8b2ob2o\$b5o2b4o4bo\$bo3b4o3bo\$5bob2o\$bo3b3obo\$2b3o4bo2bo\$2b2ob2o4b3o\$2bo4b4o3bo\$7b2obo2bo!`

Edit: here we go:
`x = 14, y = 16, rule = B2in3aeijn/S234ebo\$b2o\$bob2o\$o2bob2o\$o2bo2bo4b2o\$6bob2ob2o\$6bobo4bo\$5b2obo\$5b3o\$5bo2\$7b3o\$10bo\$5bo3bo\$6b2o\$5bobo!`

Also, it features in this c/3 from testitem's c/3 collection on the first page:
`x = 19, y = 27, rule = B2in3aeijn/S234e4bo9bo\$3b4o5b4o\$2bo3b2o3b2o3bo\$3bo4bobo4bo\$5b2obobob2o\$5b2obobob2o\$6b2o3b2o\$4bobo5bobo\$4b3o5b3o\$4bo2bo3bo2bo\$3bo11bo\$3bo11bo\$5b3o3b3o\$6bo5bo2\$2b3o9b3o\$5b2o5b2o\$bo3b2o5b2o3bo\$2b2obo7bob2o\$5b2o5b2o2\$6bo2bo2bo\$b2o5bobo5b2o\$b2ob2obo3bob2ob2o\$o3bob2obob2obo3bo\$4b3o5b3o\$5b2o5b2o!`

Doh! I missed that...

Here's an xs34 (sequential aft xs33) and an xs36 (record breaker) in C1, and the producing reactions:

`x = 57, y = 19, rule = B2in3aeijn/S234e43b2o\$4b2o37b2o\$4b2o3\$50bo\$49bobo\$41bo7bob3o\$2bo36b2ob2o10bo\$2ob2o35bobo7b2o2b2o\$bobo37bo8b2o3b2o\$2bo6bo41bobobo\$8b3o36b2o4b2o\$7b3obo34b3o2bo\$7bo3b2o33b3o2b2o\$7bo3bo34b2o3b2o\$7bo3bo35b5o\$9bo38b3o\$49bo!`

I'm internally calling this rule "Hatlife" every time I see one of these kinds of still lives...

### Re: Whichlife (B2in3aeijn/S234e)

This might be doable in 7G, but the pre-blinker and century both have to be synthesized at a very precise time... probably 8G.
`x = 8, y = 16, rule = B2in3aeijn/S234e2o\$o2bo\$b3o\$2bo\$6b2o\$6b2o4\$5bo\$4bobo\$3bo3bo\$3bo3bo\$3bo3bo2\$4b3o!`

EDIT:
synthable if we can make that 7-cell spark
`x = 7, y = 15, rule = B2in3aeijn/S234e3bo\$3bo\$3bo\$bo3bo\$o2bo2bo\$o5bo\$b5o\$2b3o\$3bo4\$2b3o\$3bo\$2b3o!`

EDIT:
Why aren’t there any p34s in this census?

All the other censuses besides the 3rd and 1st least searched censuses have it.
