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: As far as I'm aware, you can actually still save lives for something like £500 each by donating money to help with malaria in Africa. But *nobody does this*!
gollark: Because it is! It mostly works fine!
gollark: People talk a lot about how terrible capitalism is, and then generally just... ignore the possibility of charity.
gollark: The market system (roughly) satisfies people's values, and apparently most people's actual values don't include giving up anything to help people they don't directly interact with.
gollark: Well, yes, it isn't perfect, through broadly speaking I think stuff like people not getting food is more down to people not caring than the structure of society.
