Pentadecathlon on thumb 1

Pentadecathlon on Thumb 1 is a period-45 oscillator composed of a pentadecathlon and thumb 1. Although it consists of two oscillators of smaller periods (15 and 9 respectively), it is considered non-trivial, because it contains a single cell that oscillates at the full period. In terms of its 48 cells, it is the smallest known non-trivial period 45 oscillator.

Generation 5 reveals the single cell that oscillates at the full period (in green).
gollark: I was already doing that. I don't think it helped.
gollark: Yes, and?
gollark: 1 million iron ingots is very necessary.
gollark: Quarries are always good because number go up.
gollark: But I think it's net-positive.
