Post by **iNoMed** » November 25th, 2021, 9:31 pm

Crossposted from the Discord, here's some minor improvements to the period-68 gun (1-column bumper consistency improvement by me, 2-row H-to-2G catalyst improvement by Kazyan):

this is awesome! we should start exploring what that traffic light catalyst can do. i'll start testing it on the U-turner.

Well, congrats on obsoleting pretty much everything made based on p46 technology for the last 50 years... that wasn't already obsoleted by tech using Tanner's P46, at least.

Catagolue seems to suggest this is now the second smallest gun by bounding box, period, not counting boring stabilization variants of the GGG. By population (53 cells, or 49 if you remove a block), it's harder to figure out, but if I had to hazard a guess I'd say fourth smallest after Gosper, Simkin, and the P184 H'-to-H' gun.

I know people say this too much, but... strong POTY candidate?

By population (53 cells, or 49 if you remove a block), it's harder to figure out, but if I had to hazard a guess I'd say fourth smallest after Gosper, Simkin, and the P184 H'-to-H' gun.

The P156 gun only has 36 cells, which ties with the Gosper gun.

Simkin
Gosper = P156
P184 H'

The GitHub collection isn't exactly an up-to-date gun collection these days, as its main purpose has been entirely-replaced by a gun collection in Catagolue's glider-synthesis database. Anyways, here's some more-optimised versions of the three periods from your post.

The GitHub collection isn't exactly an up-to-date gun collection these days, as its main purpose has been entirely-replaced by a gun collection in Catagolue's glider-synthesis database.

I see. I have since edited the wiki pages to make this more clear that we are using Catagolue and not the GitHub collection anymore.

It might be a good idea if someone edits the first post of this thread to mention the Catagolue database as well.
