It can, by switching out the semi-snark.

I realized that the p3 catalyst in the new p57 pi hassler also works with the B-to-glider in the p57 gun. In fact, there was a bit more room for the reaction, so I was able to find something much smaller using LLS:

Code: Select all

x = 48, y = 40, rule = B3/S23

This puts the bounding box just below 2000 cells. It might be possible to make this one column narrower on the left side, but to remove two columns on the left or one on the right would require increasing the overall height of the gun.

Here is the new p3 catalyst by itself:

Code: Select all

x = 13, y = 11, rule = B3/S23

Note that there are times Rob's p16 works better than figure eight as a support for charity's p16: though it bulges out one row to the right, it can cut off two rows to the left and only exhibits a weak dot 1/2 the time.

In the above gun for instance, figure eight would be destroyed being so close to the blocker. Rob's p16 will not.

Sokwe wrote: March 9th, 2025, 4:19 am I realized that the p3 catalyst in the new p57 pi hassler also works with the B-to-glider in the p57 gun.... It might be possible to make this one column narrower on the left side, but to remove two columns on the left or one on the right would require increasing the overall height of the gun.

It is in fact possible to reduce the gun by one column on the left side:

This gun cannot be made narrower without either making it taller or finding a new p3 B-to-glider catalysis reaction.

On Discord, P1GG noted that this method also gives the following p44 gun based on the p44 pre-pulsar hassler, although it's far from being a record:

Edit: I tried to reduce the p80 gun further by allowing for different p4 catalyses to support the B-to-glider, but searches for all possible smaller bounding boxes returned negative. This means it's very unlikely that we will be able to reduce the p80 simply by replacing the p4 catalyst with another p4 catalyst that supports the same B-to-glider reaction.

Exceedingly-simple reduction to gun_19 from 115x102 (11730-cell BB) to 115x101 (11615-cell BB) by retrofitting the 47x40 engine to the lower-left engine (How the heck are all the reductions to the lower-left engine only??)

The smallest solutions for periods guntrue_5360 (80 times 67), guntrue_5680 (80 times 71), and guntrue_6320 (80 times 79) can be achieved by similar mechanisms to the Guntrue_4560 and Guntrue_4880 engines above.

EDIT 2: 1st results from the new P80 gun - reduction to guntrue_2560 (2950 -> 2862) (EDIT 3: Fixed figure eight)

I'm pretty sure you meant to put a tremi-snark instead of a quadri-snark for gun_342, in that case here is another reduction:

While not tiny, it solves the smallest prime*80 gun period that was still based on Herschels, as well as giving a LCM mechanism for sparkers with a period greater than the period of the block factory. (They still can't be coprime - see the p123n gun discussion for why).

Out of curiosity, how many Guntrue periods below 10000 have been reduced as a result of the p80 R-hassler now?

Apparently someone submitted a smaller variant of guntrue_9680:

Some x12 multiplier reductions to p80n guns (since Lifehistory is currently not allowing me to "grab" history cells, blocks are there to measure bounding box

The only x80 gun I could use the x12 multiplier to reduce: Guntrue_6720 (3720 -> 2491)

I also replaced one of the catalysts supporting 42P14 to a form that will presumably allow a 5-column reduction on the left side, whereas the previous catalyst would have only allowed a 4-column reduction.
