P130 shuttle is a period-130 shuttle oscillator found by David Eppstein on November 2, 2001, which originally needed several period 5 oscillators for support.[1] 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,[2] and this is shown in the infobox. Other ways to stabilise this oscillator using toaster and middleweight volcano are shown below.

Jeremy Tan found a 34-glider synthesis of the sidesnagger-supported version of this oscillator on January 6, 2020.[3]
