The p59 glider shuttle is a period-59 oscillator discovered by Nico Brown on November 18, 2022. It consists of four copies of a p59 dependent reflector. The oscillator can be described as a honey farm hassler, as in some phases the active part consists of four copies of a honey farm sequence.

Glider synthesis

Chris857 found a 141-glider synthesis of the oscillator on June 23, 2023, which he reduced to 137 gliders on July 12, 2023. KtT lowered the cost to 136 gliders on December 4, 2023.

Other uses of the dependent reflector

Matthias Merzenich used the p59 dependent reflector to reduce the smallest known true period 59 glider gun from a 14592-cell bounding box to a 11782-cell bounding box, as shown below.
