Re: p16. The double-sided clearance version of the p4 oscillator used in the dueling banjos-based gun is interesting, but doesn't help us accomplish anything for this application. Unrelated, here's a smaller p56 (by 297 cells). Made by replacing some p8 bouncers with p7 bouncers based on Scorbie's p...

Here's the p16 pseudo-gun shrunk by four rows, using Rob's p16.

A for Awesome noticed that rliston's G1 searching turned up something new today: this new p16 oscillator.

This oscillator now has a soup, as of a few days ago. The rotor is currently unique in C1. Perhaps it's useful. https://catagolue.appspot.com/object/xp ... c826/b3s23

Much of the work has occurred over Discord, so posterity may find this thread wrapping up rather suddenly. x = 261, y = 30, rule = B3/S23 249bo$250bo$248b3o$258bobo$251bobo4b2o$155bo95b2o6bo$3b2o38b2o48b2o48b 2o8bobo3bo43b2o38b2o7bo$2bo2bo36bo2bo46bo2bo46bo2bo8b2o2bo43bo2bo36bo 2bo$3bobo37bobo47bobo...

With some help from Blinkerspawn and some more from spark_search, here's a cheaper method of performing this expensive conversion in the spider synthesis: x = 163, y = 41, rule = B3/S23 94bo$92b2o$93b2o54bo$77bo12bo56b2o$75bobo10bobo57b2o$76b2o11b2o53b2o$ 144b2o15bo$94bo64b2o$77bobo14bobo63b2o$78b2o...

One of those involves an interaction that can be made into a component:

I nominate Goldtiger's synthesis of a c/4 diagonal spaceship. It's elegant chaos, and spaceship syntheses are rare.

"Don't like thing." : A joking phrase from the Discord server, to describe the sense that a Life pattern doesn't look like a Life pattern--it contradicts intuition. This is a subjective term, so no pattern is an objective "Don't like thing", but examples may include high-period oscillators and stil...

You can scrape synthesis costs from: https://gol.hatsya.co.uk/textcensus/b3s ... esis-costs

Synthesis costs are stored the same way B3S23 symmetries are; the values attached to each apgcode are just populated differently.

It may be worth making a script that: 1) Iterates over all objects found in this search that require at least 6G to synthesize, 2) Collects their sample soups, 3) Runs those sample soups to completion individually, 4) Checks if the final population of the soup is equal to the population of the objec...

Edit: Known? x = 32, y = 25, rule = B3/S23 30b2o$22bo7b2o$21bo2bo$20bo3bo$20bo3bo$15b2o3bo$15b2o8bo$21bo$26bo$11b o4bo5bo3bo$8bob3ob2obo4bo3bo$7b3o4b2obo4bo2bo$8b2o6bo7bo5$15b2o$15b2o 3$7b2o$3o4b3o$3ob3obo$5bo! To my knowledge, and according to the jslife collection, this is a new hassling mechanism.

A component, reverse-engineered from the soup of a half-bakery derivative:

Request: a script that retrieves the apgcodes of all Catagolue objects that 1) are half-bakery derivatives, such that all state-2 cells below are dead and all state-1 cells below are alive, and 2) have at least one C1 soup. x = 7, y = 7, rule = LifeHistory 4.2AB$2.BA2BA$.2BABAB$.2ABAB$A2BAB$ABAB$BAB!
