Small Unnatural Objects Watchlist
Posted: January 28th, 2022, 1:14 pm
This thread is intended to list what still lifes, oscillators and spaceships below a certain population threshold are yet to appear from asymmetric soups, as well as to report when they do finally emerge.
The information in this initial post is accurate as of January 2022.

Currently, only two 14-cell objects are yet to appear naturally, both p2 oscillators:

There are currently four still lifes which haven't had any natural occurrences: EDIT by Sokwe: now down to just one as of 23 February 2023
In addition, there are the following four oscillators: EDIT by dvgrn: now down to two as of 30 June 2022
16 Bits
I'm not sure as to what still lifes in specific are yet to appear naturally, however there are a total of 180 of them which have yet to appear (3106 have occurred naturally, of 3286 total).
EDIT by dvgrn: now down to 148 as of 10 June 2022
EDIT by Sokwe: now down to 94 as of 23 February 2023
As for oscillators, there are 18 period-2 oscillators of this size yet to be seen from soup:

- Cha cha: xp2_4o6o7o68zx1 (found 7 Jul. 2022 by Charity Engine; note that this was first discovered in a C2_2 soup that did not rely on symmetry to produce the oscillator, and the C1 occurrence is essentially a duplicate)

- xp2_0g4j04g53z32x3 (unknown discoverer and date; note that, like cha-cha, this did not occurr in the official C1 symmetry, but a C1 soup does exist for this pattern derived from a C2_2 soup that does not rely on symmetry to produce the oscillator)
