What I think to be the first HROT weighted mealworm rule: x = 16, y = 1, rule = R3,C2,S6,10-12,26,30-31,51-52,55-57,60-62,B27,30,32,52,56-57,62,NW00000001000000000000050000000000001900000001051900190501000000190000000000000500000000000001000000 6ob9o! Are there any more mealworm ships in this rule? ...

can you tell me the period of this basilisk? x = 56, y = 1, rule = B2e3ci4at5aj6/S1e2i3ei4et5aiy6cin78 56o! This does not seem to be a basilisk (as defined in the OP). This is a predecessor of a period-1364647 oscillator and some leftover ash. The minimum population phase of this oscilaltor seems t...

Doubleposting but I feel that this warrants a doublepost. Pruning rulespaces It would make sense to treat the semi-totalistic condition A0 and all conditions that are a subset of semi-totalistic condition A1 as untoggleable, as B0/Dn (where n is the neighbour count in the neighbourhood) rules are ge...

Double posting, but it's been a month. Behold, a 2-state 1D rule which is semi-totalistic under the (maximally symmetric) 1D neighbourhood where: - two neighbours are at distance 1 from the central cell - two neighbours are at distance 3 from the central cell with five small unadjustable ships of fo...

One reasonably small space is "2-state isotropic CA on the hexagonal tiling using honeycomb neighbourhood, and with the added restriction that the current state of the middle cell is not considered when deciding on its future state". [...] You are right, I didn't consider the class of isotropic cel...

I have been pondering about the question: what rulespaces are small enough such that every rule in it can be explored systematically in a reasonable amount of time, and if so, what objects can they contain? This question is ill-defined (depending on what 'systematic' and 'reasonable' means), but I s...

[...] small one-per-generation patterns which use at most one infinite growth mechanism (most likely a wickstretcher engine).

It is trivial to make one-per-generation patterns (and by extension, n-per-generation patterns where n is some natural number) using guns or wickstretchers. Like you showed, many such patterns are clunky almost to the point of being contrived. A better use of this thread, arguably, would be to compi...

76c/497. Apgsearch thinks its period is 9 times that because it puffs p9 oscillators.

Fixed. Thanks!

State-2 cells in CataProp2 emulate B2ci3ai6c/S02aci3i4cetz6ci8 (proof: the below soup is in fact a De Bruijn torus ( source ) that contains every single possible 3x3 configuration of on-or-off cells, so this soup will behave differently in every rule in the range-1 INT rulespace). x = 32, y = 16, ru...

What is DECAHOPPER?

I reckon it's COPPERHEAD.

What would be the 'interesting' interactions between the soup searcher and the spaceship finder? Would they run more or less independently (probably sequentially, to reduce peak memory usage), or there would be some sequence of searches with results of earlier searches used to decide what to do nex...

So far, many search programs have been created to search for patterns. In fact, that is the objective of almost every search program. However, what if a conglomerate of these programs can be made, to ultimately create an automatic explorer that finds patterns in a rule? It would save much time, and ...

Catagolue census I can't resist posting this rule, as it has a few interesting high-period objects.
