P130 shuttle is a period-130 shuttle oscillator found by David Eppstein in March 2004, which originally needed several period 5 oscillators for support. David Bell found a reaction between two of the shuttles to produce a p130 glider gun. On 18 November 2017 Tanner Jacobi found that the stable sidesnagger can be used to support the shuttle instead, and this is shown in the infobox. Other ways to stabilise this ocillator using toaster and middleweight volcano are shown below.
