The bs123 census contains everything needed.
(what's going on with catagolue? with url tags chrome screams at me that it's not secure but with catagolue tags it happily swallows the certificate don't login with the link above it's http the others are https)
Ian07's project for islands can be found here.
A table on the wiki will be coming shortly.

Improvement to xs4_27 (xs13_j5c4goz11):

Code: Select all

Also, the bs23 census is not all that is needed because you can have things like this (right?)

Code: Select all

x = 33, y = 9, rule = LifeHistory
23.C$13.C4.C.C3.C4.2C$C5.2C4.C6.C5.C5.C3$24.2A4.2C$CA4.2C5.C5.A3.C2.A

Why do we need bs23 census? Actually important is the bs123 (or whatever) only, since it's perfectly possible to have cells with one neighbour.

fixed.

EDIT: User:Bubblegum/Patterns/SSLWSM now contains the table!

this script to generate the parts:

Code: Select all

from urllib.request import *
rule = "bs123"
sym = "C1"
type = "xs4"
q = []
u = urlopen("https://catagolue.appspot.com/textcensus/{}/{}/{}".format(rule, sym, type)).read()
for i in u.splitlines()[1:]:
  i = i.split(",")[0].strip("\"")
  q.append(i)
print(sorted(q))
(python 3.x, i'm too stupid to learn python 2.x
change type to adjust cell count
