p55 pre-pulsar hassler

p55 pre-pulsar hassler is a period-55 oscillator discovered by David Buckingham on January 26, 1986[1], being the first period-55 oscillator to be found. It works by hassling a pre-pulsar with various still-lifes. The original pattern is hassled by two eater 1s, four eater 3s, and two 14-cell still lifes, each composed of an eater 1 and a bun. A reduced set of still-lifes were discovered by Matthias Merzenich in June, 2011. The new version is hassled by four eater 1s, two eater 3s, and two BTSs.

Generation 4 of the originally found pattern reveals that the object being hassled is a pre-pulsar.
gollark: Seriously, *how* do you get the "haskell" and "code here" bits out of stuff like```++exec`\``haskellcode here`\`````
gollark: $ help
gollark: I'm still trying to figure out how to parse the codeblock things.
gollark: ++help
gollark: Wow, it does equally badly on kind of generic terms.
