Bipentadecathlon 1 is a period15 oscillator, composed of two interacting pentadecathlons which symmetrically cancel each other's sparks.
Commonness
 Main article: List of common oscillators
This oscillator first appeared naturally in March 2015.^{[1]} It is the second most common period15 oscillator behind the pentadecathlon itself.
Glider synthesis
The reaction which produced this oscillator in the soup stated above later led to a 7glider synthesis of a bipentadecathlon.^{[2]} On September 14, 2022, Goldtiger997 improved the cost to 6 gliders by cleaning up a 5glider collision from Open Science Grid.^{[3]}
