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):

EDIT: Hmm, I wasn't trying very hard, obviously. Silly of me to even try using that p60, anyway, when a p30 works just as well with Paul's mechanism.

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

However, Paul did say

so I suspect minimizing the bounding box is not his goal. Even so, your glider gun reorientation does reduce the bounding box of the "simple" gun a bit:

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.

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…

Oh, excluding Gardens of Eden. And sorry, I accidentally posted this in usure discoveries thread instead of basic question thread.

A spark can extract a glider from Beluchenko's Other p37, in case we ever get a p37 sparker:

I think there's about a 50-50 chance that we could construct a true period p37 gun with today's technology; we'd just have to find an over-unity reaction.
