Another (partially unintentional) find from that search, two related remarkably simple 11-cell unstable switch engine predecessors:
Code: Select all
x = 110, y = 107, rule = B3/S23
9bo$8b2o2$7bo$3o2bo$5bo$5bo$7bo93$109bo$108b2o$107bo2$100b3o3bo$106bob
o$106bo!
They boil down to blinker+TL+v spark, which is just nice. I couldn't find any 10-cell siblings to these by hand.
EDIT: 2 generations ahead, still 11-cells:
Code: Select all
x = 10, y = 7, rule = B3/S23
8bo$7bobo$7bo2$3o3bo$6b2o$6bo!
EDIT2: Random Big S appearance (from a common fleet+blinker predecessor):
Code: Select all
x = 12, y = 18, rule = B3/S23
7bo$7bobo$8bo2$3o3bo$6b2o$6bo9$11bo$11bo$11bo!
EDIT3: Random relatives to the thing from my previous post I found manually while bored:
Code: Select all
x = 26, y = 9, rule = B3/S23
bo21bo$20b3obo$2obo19bo$ob2o17bo$2bo21bo$2b2o19b2o$21b3o$3o$2b2o19bobo

EDIT4: 14 cells!:
Code: Select all
x = 6, y = 9, rule = B3/S23
