Tanner's p46 is a period 46 oscillator that was found by Tanner Jacobi on October 20, 2017 involving a pi running a small conduit containing a PT8P and PT38P.

Synthesis

Mark Niemiec posted a trivial 19-glider synthesis of Tanner's p46 two hours after its discovery. This can be reduced to 15 gliders to produce a stator variant that replaces the two snakes with eater 1s.

Uses

David Bell used Tanner's p46 and a twin bees shuttle to build a period 46 glider gun on October 21:

The same day, Matthias Merzenich built a p46 gliderless MWSS gun using two copies of Tanner's p46. In June 2018, Nathaniel Johnston built a p46 gliderless LWSS gun using three copies of the oscillator.
