a small pattern of 3c/11 reaction

[d57799]

This is accidentally discovered while I'm playing around reactions of traffic lights and 2c/7 reactions, but it came to an distinct reaction.

Here's the original reaction:

Code: Select all

x = 16, y = 15, rule = B3/S23
4$7bo$6bobo$5bo3bo$6bobo$7bo$7bo!

Then with a simple addition it goes a period further.

Code: Select all

x = 9, y = 12, rule = B3/S23
2$4bo$3bobo$2bo3bo$3bobo$4bo$4bo$4bo!

And this is just called a "reaction" it still takes effort to make it a spaceship.Though the speed is not a strongly wanted speed

Nope, 3c/11 isn't exactly common. But noting that almost the same effect can be achieved with two gliders as shown

Code: Select all

x = 7, y = 8, rule = B3/S23
3bo$2bobo$bo3bo$2bobo$3bo$bo3bo$b2ob2o$obobobo!

with the exception of two blocks (which could be destroyed by other gliders) it could make for an interesting pattern, moving at 3c/11 with the traffic light and hassling it via rakes.

PS:
Or someone could set up a few guns to repeat this reaction in two (or more) directions
two directions shown in the code.

Code: Select all

x = 19, y = 25, rule = B3/S23
bo15bo$2bo13bo$3o13b3o2$5bo7bo$3bobo7bobo$4b2o7b2o4$9bo3$9bo$8bobo$7bo
3bo$8bobo$9bo$7bo3bo$7b2ob2o$6bobobobo2$3b2o9b2o$2bobo9bobo$4bo9bo!

A hassler shunting it in to directions with guns producing gliders of the appropriate period would be p22.

A oscillator based on this reaction seems possible with four gun in each direction. But the distance between the two gliders is noticeably close that finding a small gun shooting that way might be hard. while a p22 oscillator has been discovered, and with only 36 cells, this larger one is comparatively less useful.

But in terms of constructing a spaceship, this speed is rare. It will be fantastic to find a spaceship in this speed.

By the way, there are more speed that everyone is eager for, including myself. For instance, a 3c/7 spaceship is almost discovered, and I have even higher expectation on a 3c/7 one than a 3c/11 one.

here's the discussion of the 3c/7 pattern:

both speed is charming!

I think it would be possible to get the gliders close enough if one used a reflector for one of the streams

For an oscillator that shuttles the pre-traffic-light back and forth, the whole oscillator is period 22, and period 22 glider guns currently exist., so this should be possible using existing technology. For 3c/11 spaceships, however, some different mechanism would need to be used (for example, one that advances 6 spaces every 22 generations), as it's physically impossible to get streams of gliders separated by 11 generations - 14 is the bare minimum.
