Pentadecathlon on 37P7.1

Pentadecathlon on 37P7.1 is a period-105 oscillator composed of a pentadecathlon and 37P7.1. Although it is composed of two oscillators of smaller periods (15 and 7 respectively), it is considered non-trivial, because it contains two cells that are alive in generation 50 and dead in the other 104 phases of the oscillator. In terms of its 49 cells, it is the smallest known non-trivial period 105 oscillator, followed by Pentadecathlon on 38P7.2 with 50 cells.

Generation 50 reveals the two cells that oscillate at the full period (in green).
gollark: Oh, I guess that's true.
gollark: They would?
gollark: RSAPI, for instance, relays my RSS feeds to Discord, bridges some alerts, handles some types of reminder, posts NASA's astronomy picture of the day in the RSS thing, handles fortunes for potatOS, bridges DNS to IRC and the comments system, bridges OIR™ things to other things, contains the webmaze, and contains a youtube-dl frontend.
gollark: Most of my private stuff is code for my problems.
gollark: Retroactively proactively.
