p49 glider shuttle
The p49 glider shuttle is a period-49 oscillator discovered in its original form by Noam Elkies on August 1, 1999,[1] and was the first period 49 oscillator to be found.[2] It consists of four p7 bouncers reflecting four gliders around a period 49 track. In the infobox a slightly smaller pipsquirter 2, found by Karel Suhajda on January 24, 2003, is used.

In terms of its 400 cells, it was the smallest known period 49 oscillator until the discovery of Snark-based adjustable glider loops in 2013. Currently the p49 bumper loop with 206 cells is the smallest p49 oscillator.

gollark: Assuming the trespassers are paramagnetic, I mean.
gollark: I mean, it would be quite easy to use the orbital trespasser magnets™.
gollark: IIRC it isn't actually that lambda-calculus-related, since you can just do "bind [opponent health] [deal damage]" or something like that.
gollark: I do know roughly how it works.
gollark: Or for anthropic reasons.
