Travelling Ts(b3s23-a5) and its variants

[LuveelVoom]

Those are fuses, not crawlers. A crawler has to be reuseable (outputs it’s own still life or oscillator base behind it).

[mmmmmmmmm]

Doing some more work on the boat and T reaction, found this thing that shifts the boat 2 cells, but very quickly.

Code: Select all

x = 12, y = 9, rule = B3/S23-a5
7b2o$7bobo$2o6bo$obo$b2o3$9b3o$10bo!

This one makes a C, which is useless but interesting.

Code: Select all

x = 12, y = 13, rule = B3/S23-a5

Another fuse, this one is very dirty:

Code: Select all

It produces a lot of spaceships, so although unlikely, perhaps we could make a self-supporting spaceship from it?
Also, hc0, I have noticed you have done some hauls for this rule. But unfortunately, the version you are using has bad separation and keeps recognizing groups of spaceships as 1 spaceship. If you are going to do hauls, please try to use a version that does not have faulty separation.

[mmmmmmmmm]

How many spaceships are known in this rule that are 20 cells or less?

How many spaceships are known in this rule that are 20 cells or less?

for c/2 there are 8:

I am considering renaming this thread to "Travelling Ts and its variants", because I want to investigate B37/S23-a5 (C doesn't work), and B3/S23-a57 (more chaotic). Can someone apgsearch B37/S23-a5 and B3/S23-a57?

Code: Select all

x = 0, y = 0, rule = B3/S23-a57
!
[[ RANDOMIZE ]]

[mmmmmmmmm]

both of those new rules seem very interesting, and if you made this thread travelling Ts and its variants then i will contribute to both new rules. For example, there is a simple T insertion that has the minimum repeat time possible in B3/S23-a57:

Code: Select all

x = 14, y = 11, rule = B3/S23-a57

I have been doing some c/3 searches in RLifeSrc, and have proved 3 things in this rule:
A c/3 spaceship must be at least 9 cells long.
A c/3 spaceship must be at least 13 cells wide.
A c/3 spaceship cannot fit in a 15x15 bounding box.
I also found a 9-cell long c/3 spaceship, proving that 9 cells is the minimum length for a c/3 spaceship:

Code: Select all

x = 61, y = 9, rule = B3/S23-a5

At 132 cells, it is pretty small for a c/5 spaceship. Note: the search did not find the spaceship directly, it found the left 3/4 of it and could not complete it because it was doing a 9x50 search.
Also, here is a p50 'p25s hassling big blinker' smaller than the one on SKOPs.

And a p75 (25,3) LCM:

Can someone do another search for c/7? We only know one, so finding another would be cool.

I did a 16x16 search for c/3 spaceships, no results. It took over an hour and a half, so I am not going to be able to do a 17x17 search. Later, I will do a search to see if the c/3 I discovered is the thinnest possible that is 9 cells long.

Can someone please apgsearch b37s23-a5 and b3s23-a57? I want to see what interesting patterns appear in these variants of travelling Ts.
Lastly, I gave some of the spaceships names, but only the natural ones, of course.
This is the C with flap:

Code: Select all

This is the bee:

3bo$2b2o$5bobo$3o5b2o$5bobo$2b2o$3bo!

Code: Select all

x = 8, y = 10, rule = B3/S23-a5
b2o$2ob2o$2obo2$3bo$5bo$4bob2o$4bobo2$6bo!

For now, it is 17P2H1V0.
Interestingly, the C with flap is more common that 17P2H1V0 in C2_2, but less common in C1. Probably just a random thing, but still interesting.
The bee is around 1 in 1.55 billion, 17P2H1V0 is around 1 in 1.6 billion, and C with flap is around 1 in 1.95 billion.

[mmmmmmmmm]

R2INT, can you get C1 to 8 billion (or even 9 billion) objects? Also, can you get C2_4 to 100 million objects? I want to see another spaceship appear naturally, and also if any new objects appear. You never know, perhaps there is some prime period oscillator with C2_4 symmetry in this rule, just waiting to appear.
Anyone else who would like to help, please do! (but please use v5.x, as the separation is terrible in v1.x).

At the south of the pattern, glider guns will create the salvo of Ts, but there will be some additional mechanism which prevents the creation of all of the Ts (perhaps T guns aimed at one of the T-creating gliders). The returning T will be reflected and remove all of the Ts that shoot down the gliders, which causes a salvo of Ts to be fired at the receding c/5o spaceship. Since a T is fired to the east each cycle, the population should grow proportionate to O(log N).

Interesting. I am going to do some work on that later today.
Also, we will probably only need 1 or 2 blocking guns, because you can make the first collision leave debris that the second one has to destroy.

Making a sublinear growth pattern from that would be difficult, as the T ends up on the same lane that it started on.

Is there any way to make it work?
Edit: At least the oscillator can reflect gliders:

Code: Select all

x = 79, y = 16, rule = B3/S23-a5

Unfortunately not, but you can make a p96 gun: (a p32 gun with p48 filter)

Code: Select all

x = 129, y = 94, rule = B3/S23-a5
