Statorless (B2ek3i4c/S12cek)

[635318657]

Hello everyone!

This rule is the isotropic minrule of the following oscillator, which we shall call the O:

Code: Select all

x = 5, y = 5, rule = B2ek3i4c/S12cek
2bo$bobo$o3bo$bobo$2bo!

Sample soup:

Code: Select all

x = 100, y = 100, rule = B2ek3i4c/S12cek

Still lives:

By far the most common still life is the domino. Other still lives also exist, such as the following extensible one:

Code: Select all

x = 8, y = 2, rule = B2ek3i4c/S12cek
2bo2bo$2ob2ob2o!

Oscillators:

This rule is named after its two most common oscillators: the statorless p7 above and the following statorless p12 (the L):

Code: Select all

x = 3, y = 3, rule = B2ek3i4c/S12cek
3o$2bo$2bo!

There's also a statorless p16 (the N):

Code: Select all

x = 5, y = 4, rule = B2ek3i4c8/S12cek
ob3o$4bo$obo$bo!

Some oscillators have a stator, like this p2:

Code: Select all

x = 5, y = 3, rule = B2ek3i4c/S12cek
2ob2o2$2ob2o!

Spaceships:

The two most common spaceships are these:

Code: Select all

x = 9, y = 2, rule = B2ek3i4c/S12cek
bo4b2o$obo2bo2bo!

The left one shall be called the V and the right one the B.

Misc:

All 2V collisions that produce something:

One of them produces a B. It is surprising to me that none of them create an oscillator.

V + B synths of the O and the L:

o$bo$o2$7bo$6bo$6bo$7bo8$o$bo$o4$2b4o$2bo2bo!

A B costs 2V, so these can be made into 3V synths.

Code: Select all

x = 17, y = 6, rule = B2ek3i4c8/S12cek
14bo$14bo$14b3o$2o$bo$2o!

Welcome back!

It's better to share a rule in Miscellaneous Discoveries in Other Cellular Automata before creating a thread for it, only after there're at least a few posts (I prefer 3) about it. If everyone on this forums creates a thread for every single rule they find, the server will quickly shut down afterwards due to too many threads.

Do you mean the 4c/16 growth is on catagolue? I put it there. There were no soups with it when I uploaded the first results from shipcolls. https://catagolue.hatsya.com/object/yl8 ... i4cs12cek It also doesn't appear in the thread. Could you link to an earlier mention of it?

So not mentioned here, and not in the database in the form shown. New. At worst new enough that it doesn’t need a vague correction. It's annoying to get nothing but a dismissive response when I'm posting something not documented to your thread.

This is a small one from rlifesrc, but there are seminatural examples in many symmetries (including D4_+2 which was searched early on by silversmith)

It has expansion factor 19. It attains its minimum population of 91 at tick 156 * 19^n - 156 and 156 * 19^n - 84 for all nonnegative n.

Is there a sawtooth with a lower minimum population?

Here's a caber tosser which could help with such a sawtooth:
