Eater eating pentadecathlon is a period-15 oscillator which involves an eater 1 consuming domino sparks emitted by a pentadecathlon.
With a minimum population of 19 cells, it is the second smallest period-15 oscillator after the pentadecathlon itself.
The eater 1 can be substituted with any other still life capable of performing the same eating reaction. The only known 21-cell period-15 oscillator (ignoring pseudo-oscillators), referred to as integral eating pentadecathlon, involves it being replaced with an integral sign.

Commonness
There are about 4 million regular pentadecathlons for every one with an eater attached. The eater:integral ratio is approximately 5:1.
Glider synthesis
The eater 1 can be constructed via two gliders. The current synthesis of the eater eating pentadecathlon uses a four-glider synthesis; this is presumably due to the eater interfering with the three-glider synthesis which is more commonly used.
