[LaundryPizza03]

This is a rule I found manually by searching for a kickside reaction. By itself, it's fairly mellow with a random 1024*1024 torus settling in about 150-250 generations and a density of roughly 3.85±0.5%. (I used only 5 soups; someone please give better estimates.) Here are the links to my three posts in the miscellaneous discoveries forum:

Post 1:

• The gun
• Kickside and kickback reactions
• Candidate memory cell
• A gun combo

Blinkerspawn's post:

• Period doubler, tripler, quintupler (based on my gun combo), and octupler

(My) post 2:

• Complation of 2U collisons (28 distinct) by product
• The twin ship
• A soup producing the gun (not really that surprising, given its small size)
• Compilation of U+domino and U+duoplet collisions (8 each, by product)

Post 3:

• One-time 90° reflector
• The c/2 wave
• An agar built of c/2 waves
• A 5U synthesis for the twin ship
• Some open questions

This is almost certainly nothing exhaustive at c/2, but I suspect there are no ships at any other speed of a searchable period.

It seems the period tripler doesn't work for higher-period guns:

Nor does the period quintupler.

A p36 8-barrelled gun came out of soup:

The dipoles cause a two-generation offset during the first cycle, so 4 U's are emitted at alternating intervals of 19 and 17 generations. Here's the soup in which it was found:

Bump

I decided to come back to this rule and try again on the twin ship gun.

First, I found a period doubler that does work for arbitrary-period guns (here the original p17 and Blinkerspawn's p51):

Code: Select all

x = 62, y = 68, rule = B2c3aeny4a5i6i7e/S12a3ejry4etz5y6c8

Second, I found a twin ship synthesis that uses 1 more U than the original, but should be easier to implement in a gun. Plus, the rightmost U could be replaced with a variety of other ships with the same starboard.

Code: Select all

x = 40, y = 40, rule = B2c3aeny4a5i6i7e/S12a3ejry4etz5y6c8

EDIT: At last, a twin ship gun, with period 102:
