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 of 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. However, the version with pipsquirters has slightly more clearance.

The small size, rare period and spark output of the oscillator allow it to be used in the construction of the smallest known oscillators of several periods, shown below.
