44P7.2

44P7.2 is an unnamed period-7 oscillator discovered by David Buckingham on June 19, 1977.[1] In generation 6 it supplies two accessible domino sparks, allowing this oscillator to be combined with other oscillators to form non-trivial oscillators of higher periods.

Generation 6 of 44P7.2 showing two domino sparks
gollark: I used ctypes to avoid the MAX_YEAR thing once.
gollark: I did. Obviously I'm already aware of such technology.
gollark: Before making assertions about group theory, I always make sure to check if I'm dreaming, just in case.
gollark: Or put in the neat thing for positive numbers with a conditional. Although I guess you'd still need both code paths.
gollark: Just use the magic incantation "without loss of generality".
