Generations rules without B2

[Saka]

I wanted to see what people could find in generations rules that don't have b2, for example:

Code: Select all

x = 6, y = 8, rule = 23/3/10
4.H$2.FG.I$.EG$D2G$.AG.D$A2BE2A$.ABDBA$2.3A!

or

Code: Select all

x = 44, y = 38, rule = 23/345/5
10$8.A$7.AD2A$7.B2DBA$8.C2BCA$9.AB2D2A$10.AB2.3A$12.C.A2BA$13.D.A2CA$
16.A2D2A$17.B2.3A$18.C.A2BA$19.D.A2CA$22.A2D2A$23.B2.3A$24.C.A2BA$25.
D.A2CA$28.A2C2A$29.B3A$30.2ACA$31.B2CA$32.2A!

and

Code: Select all

x = 8, y = 8, rule = 23/345/5
5.A$4.ABA$3.A2BAD$2.2A.A$.AB$A2BA.D$.2A$2.D!

my other discoveries are:

There are a lot of these. Interest doesn't seem to have been very high in the last few years, but here are some older discussions you might enjoy checking out (for themselves, or for inspiration on where to explore):

Also, I do not recall if I've posted this before, but here is an interesting "widening puffer" in a variant of your 2nd rule:
[edit] sorry, doublechecked the rule and pattern:

Code: Select all

x = 20, y = 20, rule = 02378/345/5
2.2A$.ACD2A$.2A2.2A$.CA2.C2A$3.A2CA$2.A2BA$2.3A$3A$2A10$18.2A$18.2A!

Let this run for a while, and you'll see it craft some surprizingly intricate patterns.

(I think it's subquadratic in some interesting fashion.)

*runs that pattern*
Hey, that looks familiar...
*checks*
Yep, that's the same rule that has that one fractal pattern (which is discussed a little bit more here.)

I found a rule that has SO MUCH EATERS:
23/36/4

[Billabob]

I found a rule that has SO MUCH EATERS:
23/36/4

The culprit here seems to be the Pi-heptomino:

Code: Select all

x = 3, y = 3, rule = 23/36/4
3A$A.A$A.A!

I've also noticed some veeery long ships appearing when I scribble with Golly's pen tool.

[Caenbe]

Mazeon (123/3/3)
Similar to Maze, but the clouds take an eon to settle.
Gert (2368/357/3)
The r-pentomino and t-tetromino are (or technically, evolve into) spaceships. Named for Generations + r + t.

A kickback:

Code: Select all

x = 13, y = 35, rule = 2368/357/3
A$2A$A28$8.3A$7.A2BA$7.AB2.BA$9.A2BA$9.A2BA!

A one-time reflector:

Code: Select all

x = 30, y = 5, rule = 2368/357/3
.2A$.2A26.A$4A24.2A$.2A26.A$.2A!

An r duplicator:

Code: Select all

x = 12, y = 30, rule = 2368/357/3
8.2A$8.A$11.A$10.2A24$.A$.2A$2A!

I'm no expert, but I think there are probably more useful reactions in this rule, due to the simple shapes (and hence commonness) of the ships.
