42P14 is a period-14 sparker oscillator found by Mitchell Riley on September 17, 2022. It can be used as a delayed dot sparker or as a more complex spark.

The object being hassled is Thompson's methuselah, a 6-cell pattern named in Lifeline Volume 4. Thompson's methuselah is not that common, but it appears here. The catalyst is ship+fishhook.

On August 30, 2023, Chris857 found a 32-glider synthesis, which Carson Cheng quickly improved to only 14 gliders.[1][2][3]
