Score! (I think.)

Code: Select all

x = 17, y = 18, rule = sansdomino_s13
14bo$14bobo9$2o$2bo4$11b2o2$11bo!

Scanning for "two-quadrant" constructions, I got up to this with 4 gliders:

Code: Select all

x = 21, y = 20, rule = sansdomino_s13
14b2o2$14bo2$12bo$13bo$13bo3$20bo$19bo$19bo7$2o$2bo!

This also turned up a nice 3-glider synthesis for the p28:

Code: Select all

x = 8, y = 8, rule = sansdomino_s13
2b2o2$2bo2$o$bo5bo$bo4bo$6bo!

p28 phase-shift reaction:

Code: Select all

x = 18, y = 11, rule = sansdomino_s13
16bo$16bo$17bo6$3bo$ob4o$3bo!

A few simple hasslers:

Code: Select all

x = 58, y = 47, rule = sansdomino_s13

Gun period multiplication using one of the 6-cell still lifes (suggesting name: mirror):

Code: Select all

x = 55, y = 55, rule = sansdomino_s13

(I'm also running various glider-on-object collisions…)

Just found a somewhat weaker but faster version of my three-glider pipsquirt:

Code: Select all

x = 16, y = 12, rule = sansdomino_s13

Back in February, earlier in this thread, I said "I wonder if any of the many patterns from the Just Friends rule work in any of these rules?"

The answer is yes. In particular, JustFriends is SansDomino_S12!

I'm (slowly) getting ready to make a series of posts on non-totalistic rules, but for now, if you're not already familiar with JustFriends, you are sure to enjoy David Bell's collection here:

It is also interesting to compare the ruletable for SansDomino_S12 posted in this thread with the JustFriends ruletable found at the Ruletable Repository:
