I removed the eater here because it is unnecessary; it only counts as an improvement if an even number of the lower gliders are removed. (neither the eater with feather nor the eater-with-feather cis-tie aircraft carrier fit)

You can add more loaves by rewinding the gliders that ignite the guns, but in the current form they can only be rewound a generation or two.

I notice that there's a constellation whose sole purpose is to absorb a dying spark and produce a delayed SEward glider:
CODE: SELECT ALL / SHOW IN VIEWER

x = 8, y = 7, rule = LifeSuper
.2O3.2O$2.O4.O$2.O.3O$.2O.O$O2.O$2O4.2O$6.2O!
Would it be possible to eliminate this completely, and instead have the SEward glider be produced by modifying this constellation?
CODE: SELECT ALL / SHOW IN VIEWER

x = 12, y = 10, rule = LifeSuper
10.2M$11.M$8.3M$4.O3.M$3.O.O$3.O.O2.O$4.O.3O$.O3.O$O.O3.O$2O3.2O!
Because this is triggered later in the shutdown, there's no longer a constraint to delay the SEward glider; it can appear at any time.

This was a quick hack. My intention has always been to trigger the final cleanup of the remains of the Simkin gun at the bottom with a spaceship from straight above. This was looking difficult so I implemented the available quick glider cleanup, which took a short while to set up and about a second of computer time.

My search for a spaceship based cleanup succeeded after a while:

This has the exact same initialization as Toroidalet's last post, but it lasts 660 ticks longer at the very end. This is because the spaceship destructor is triggered 132 ticks later and the multiplier is 5. Here is the shutdown sequence:

It has been mentioned that a 32x32 diehard would more or less fit in the open space now. While this is true, it would be a fair amount of engineering to get it to work. I am currently thinking more along the lines of trying to turn the following design based on Pavgran's into a diehard:

While it is not "light and airy" like the current design, it is significantly smaller. I am also investigating modifying the current design by replacing the three hour tour that the gliders go on with another Simkin gun at the top.

Have a happy day,

(I've occasionally wondered how the diesuper^^duperhard progression would have gone, if somebody had successfully objected early on that diehards "didn't count" if they didn't actually fit inside a 100x100 box.)

Well, we could just use tons of sawteeth 195s and connect each of them such in a way that when the block reached the first sawtooth 195, it just created a glider which would be burning through a tub fuse, eventually enabling another sawtooth 195 to create a block, and only then the loaf fuse gets involved. That way, we could get pentation involved. ANd we could replace every simkin glider gun with a sawtooth 195 that released a glider whenever the block reaches the body. Ha!

Good luck getting more than one or maybe two sawteeth in a 100×100 bounding box.

Another one to achieve a value of 1815267490816347576. EDIT: Rewinded guns to get a value of 1826659985823844806.

Incorporated optimisations from the 60x60 diehard to bump the value to 2510209686273678606. There might be a way to insert a block after the ship near the eater. EDIT: Done to make the lifespan 2738059586423623206. I'm currently working on upgrading the block to a ship.

Is this actually a diehard? If i remove the loaf fuse, it leaves behind debris at the end.
Edit: Of course, i also need to remove the fuse lighter.

The c/5 gets hit the second time (first time after the loaf fuse burns) at around generation 1.5724 million. I'm guessing this means the lifespan is around that × 121^13097 ≈ 2.7324 × 10^27284. Maybe someone can do a more precise calculation.
I wonder if HashLife could simulate this entirely. Golly starts being slow at around 2^2000, but i don't know how bad the overhead of real-time rendering is.

On the table on the wiki, there is currently a huge gap between n=32 (caber-tosser-based, 1.12 million generations) and n=53 (sawtooth-based, 2.51 quintillion generations). Should we try to fill that gap? At the very least we could extend the caber-tosser design. Also, considering the 32×32 one doesn't use any space-dust strats, maybe it can be compacted a bit.

[calcyman]

My intention has always been to trigger the final cleanup of the remains of the Simkin gun at the bottom with a spaceship from straight above. This was looking difficult so I implemented the available quick glider cleanup, which took a short while to set up and about a second of computer time.

My search for a spaceship based cleanup succeeded after a while:

Thank you so much! With this modification, it's possible to fit both a NW-ward c/5d spaceship and a pure glider generator in the top corner:

I've also taken the liberty of spacedustifying the relevant areas. This means that it suffices to build a decent 32x32-style diehard in the top-left corner which produces a glider with the correct lane and mod-120 phase as the solitary glider shown on the far left of this pattern.

That said, I agree that your approach of shrinking Pavgran's tetrational sawtooth will ultimately be more fruitful, because it may allow more block destroyers (which vastly outrank everything else) to be incorporated.

Is it possible to do something like what Pavgran tried to do a while ago and replace the northwestern queen bee with a longer line of obstacles for the gun to eat through?
(the edge-shooting reaction there doesn't work with the current cleanup)

I say that would arguably be a waste of space.

Can we add a crystal to some part?

But what's the highest generation count we can get out of a LifeViewer-compatible diehard?

[dvgrn]

But what's the highest generation count we can get out of a LifeViewer-compatible diehard?

Let's see ... with MAXGRIDSIZE 14, I think I could safely bid on at least 2^100000 times some base gun period, based on the time-honored method of rigging up a chain of period multipliers to self-destruct in reverse order once that many signals have worked their way through the chain.

I'm not sure exactly how tightly quadri-Snarks can be packed once they're seeded for destruction. But I think that a simple calculator pattern (like the pi calculator, but with all modern miniaturized components) could count to a number higher than 2^100000 on a bank of linear binary memory devices.

It would be great to have a modern rebuild of the 2D memory device in Osqrtlogt, so we could see how big that would be. Seems like it would very likely fit in LifeViewer, though it would be extraordinarily boring to actually watch it running there for any significant number of ticks.

[confocaloid]

An idea for another challenge: make a "tetrational diehard puffer" spaceship that can be run in Golly. (The diehard is going to be bigger and less long-lived, though)

[...]
Technically, yes, we know exactly how to make a puffer for anything that we have a glider synthesis for. (Or it would be a rake if the constructed object is a spaceship, or a quadratic-growth pattern if the object is a rake, or a spaceship if the object is a diehard, etc., etc.)
[...]

more ticks to the 10,000-cell diehard:
