Acorn is a methuselah found by Charles Corderman. It was discovered no later than 1971[1], though its exact year of discovery is unknown. Its maximum population, 1057, occurs in generation 4408.[2] Also, it is composed of 2 or 3 sparks, depending on how the left side is looked at. Despite this, 4 gliders are required for synthesis. The left spark can be flipped to create another "isomer," that evolves the same way.

Stable pattern

The stable pattern that results from the acorn has 633 cells and consists of 41 blinkers (including four traffic lights), 34 blocks, 30 beehives (including one honey farm), 13 gliders, eight boats, five loaves, three ships, two barges, two ponds and a mango.[3]
