Iwona is a methuselah with a lifespan of 28786 generations that was found by Andrzej Okrasinski on August 20, 2004.
The stable pattern that results from Iwona has 3091 cells and consists of 213 blinkers (including 21 traffic lights), 196 blocks, 143 beehives (including nine honey farms), 47 gliders, 34 loaves, 31 boats, nine ships, six ponds, six tubs, three barges, two ship-ties in the form of a fleet, and one paperclip.
Initial active region
The initial six-cell active region, for lack of a better name, is sometimes called the "Iwona active region". It is common enough and active enough to be used in conduits, but extremely little has been attempted.
