p40 pre-pulsar hassler is a period-40 pre-pulsar hassler oscillator discovered by an unknown person. It has 160 cells in its minimum phase and is composed of four pre-pulsars with eight figure eights on the outside. It is not a shuttle, as it doesn't get pushed back and forth as a pre-pulsar.
The p40 pre-pulsar hassler first occurred semi-naturally on February 16, 2025 by Caleb R. Hilton, although it was known long before its seminatural occurrence.[1]
On February 18, 2025, Chris857 found a 152-glider synthesis.[2][3] On July 6, 2025, he lowered the cost to 138 gliders.[4][5]
