Can it not be made smaller with Michael Simkin's small p120 gun?

Yup, that does cut it down quite a bit:

But here's a smaller one by David Eppstein from the previous millennium (if you count 2000 as the last year of the thousand years, like you're officially supposed to):

Thanks! The one with the small p120 seems to have the smallest population and the fewest exotic components, so I'm going with that.

Assuming you posted the smallest p120 gun you could find, why did this one not show up? (am I missing something?)

Correct. I'm working on simplifying my ancient extensible delay loop in the "components and contraptions" thread. It is much smaller than I ever imagined it being at time. I want a small, compact gun, but some of my criteria are more subjective.

With the latest minimization, a p120 recirculating MWSS loop seems small enough to consider in a design even if you're not looking to expand the size. Non-destructive reads become trivial and you get two streams of bit output for free.

ADDED: is there any reason not to do this at p60? I forget why I settled on p120. Sorry, not thinking clearly this morning. I assume p120 is to match the streams coming back from the best puffers I knew of at the time.

ADDED: Hmm... OK, at p60 the MWSSs don't always pass each others, sometimes they mutually annihilate. I wonder if this could be a natural computer for some linear congruential generator. I can't figure out the dynamics just looking. It may be less interesting than that and just filter it down to a p120 stream with gaps.

On a related note, I have been wondering for a while if one can fit that spark in there, I know that one can make a p60 HWSS this way, but not sure about p30... (the one p30 HWSS is quite ugly/bulky). Of course one can undo that funky queen bee welding.

This mwss-constructor is doubtless known.
x = 9, y = 6, rule = B3/S23
$bo4bo$2b2obo$b2o2b3o2$5b2o!

The two cells can be taken of a hwss.
x = 10, y = 11, rule = B3/S23
$bo4bo$2b2obo$b2o2b3o2$5b2o$3bo4bo$9bo$3bo5bo$4b6o!


With this pattern you can make every mwss-rake with periods >= 20 and multible of 4 easily.
x = 82, y = 51, rule = B3/S23

Because the rake is flat on one side, you can combine it to a nearby double rake.

Is it the time to synthesis every n-cell unstable patterns?

I know it is pointless to do that, but isn't all-still-life synthesis also useless(except a few which could be used in conduit construction)?

I also know there has to be some way to prevent those far-away glider colliding simple object.

Well, you've got Gardens of Eden, which by definition are unsynthesisable, and are also unstable…
