Gliders by the dozen

Gliders by the dozen is a methuselah with a lifespan of 184 generations discovered sometime before September, 1971 in its original form (shown below) by Roger H. Rosenbaum. It was first reported in Lifeline Volume 3. The pattern shown to the right is a predecessor of generation 1 of the original form. Its name arises from the fact that it emits exactly 12 gliders before stabilizing.

gollark: I might have to reimplement that in Macron.
gollark: It has helpful messages like "invalid token OpenSqBracket".
gollark: osmarkscalculator™ perfectly* parses maths of the form `Apinate[beeoids ^ 2 + beeoids*apioforms*cryoapioids - hexahedra^AtmosphericBeeDensity[]]`.
gollark: It's much nicer than dale-related ones (1250871298541 offense). It uses algorithms, and coding.
gollark: I wrote the osmarkscalculator™ parser lately.
