The 34P14 shuttle is the second smallest known period-14 oscillator. It was found by carybe on September 24, 2018 using apgsearch,[1] but was not noticed by a human until October 11 of that year.[2] It consists 4 blocks hassling a {bi-block + 2 loaves} predecessor. A 20-glider synthesis of this oscillator was posted by Mark Niemiec on October 12.[3]

Uses

It produces duoplet sparks, and is capable of reflecting a p28 glider stream.[4] It can potentially replace the p7 bouncer for any glider stream of a multiple of 14, as shown in the period 28 glider shuttle below:

It can also reduce the tetradecathlon, a discovery by Jason Summers on January 26, 2004, where a pentadecathlon's phase is changed -- originally by sparks from large p7 pipsquirters. A 57-glider synthesis for this version of the tetradecathlon was put together by Ian07[5] with the help of Mark Niemiec[6] and Dave Greene[7] on December 27, 2019.
