There's another monomer stablization I know, with the same clearance (wink!)

Why didn't I think of this? I wanted to claim that mine was smaller by minimum population, but even
that isn't true (they're tied).

Nice! Here it is with minimized bounding box and minimized population (for this bounding box):
Code: Select all
x = 17, y = 27, rule = B3/S23

The bounding box manages to minimize both width and height for this rotor variant.
The supporting component makes for a relatively small p7 by itself:
Code: Select all
x = 17, y = 13, rule = B3/S23

Here is a smaller variant with worse clearance based on a known p7 oscillator (top stabilization is minimum width, bottom is minimum height):
Code: Select all
x = 12, y = 27, rule = B3/S23

It can probably replace the high-clearance variant in most cases.
Finally, here is the smallest variant by minimum population:
Code: Select all
x = 12, y = 28, rule = B3/S23

It's sorted roughly by spark type. Oscillators with multiple sparks are included more than once. Unfortunately, I wasn't able to easily find all of the credits, so a few are missing.
