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,[1] and this is shown in the infobox. Other ways to stabilise this ocillator using toaster and middleweight volcano are shown below.
