Oops!

Anyway, I realized that generation 38 of teardrop is this:

Code: Select all

x = 9, y = 9, rule = B2in3aeijn/S234e
2o\$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

I’m rather surprised that in two full pages nobody has posted this potentially useful G+B reaction producing a "strange" pseudoSL.

Code: Select all

x = 1, y = 13, rule = B2in3aeijn/S234e
9b2o\$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:

Code: Select all

x = 16, y = 16, rule = B2in3aeijn/S234e
13b2o\$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):

Code: Select all

x = 15, y = 15, rule = B2in3aeijn/S234e
bo\$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:

Code: Select all

x = 15, y = 25, rule = B2in3aeijn/S234e
bo\$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.

Bump
Can anyone search for a smaller c/3 using this object to stabilize one end?

Code: Select all

x = 3, y = 3, rule = B2in3aeijn/S234e
2o\$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).

Code: Select all

x = 21, y = 5, rule = B2in3aeijn/S234e

Here's a longer partial from LLS - it's not looking very likely that there's a reasonably small solution.

Code: Select all

x = 17, y = 10, rule = B2in3aeijn/S234e

Also, it features in this c/3 from testitem's c/3 collection on the first page:

### Re: Whichlife (B2in3aeijn/S234e)

Doh! I missed that...

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

Code: Select all

x = 57, y = 19, rule = B2in3aeijn/S234e
43b2o\$4b2o37b2o\$4b2o3\$50bo\$49bobo\$41bo7bob3o\$2bo36b2ob2o10bo\$2ob2o35bo

o\$7bo3b2o33b3o2b2o\$7bo3bo34b2o3b2o\$7bo3bo35b5o\$9bo38b3o\$49bo!
I'm internally calling this rule "Hatlife" every time I see one of these kinds of still lives...

This might be doable in 7G, but the pre-blinker and century both have to be synthesized at a very precise time... probably 8G.

Code: Select all

x = 8, y = 16, rule = B2in3aeijn/S234e
2o\$o2bo\$b3o\$2bo\$6b2o\$6b2o4\$5bo\$4bobo\$3bo3bo\$3bo3bo\$3bo3bo2\$4b3o!
EDIT:
synthable if we can make that 7-cell spark

Code: Select all

x = 7, y = 15, rule = B2in3aeijn/S234e
3bo\$3bo\$3bo\$bo3bo\$o2bo2bo\$o5bo\$b5o\$2b3o\$3bo4\$2b3o\$3bo\$2b3o!
EDIT:
Why aren’t there any p34s in this census?
https://catagolue.appspot.com/census/b2 ... s234e/D8_4

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