The Iwona active region[note 1] is a semi-common evolutionary sequence in Conway's Game of Life. It got its name from the fact that it is the initial active object present in the Iwona methuselah (ignoring the blinker, two pre-blocks and a pond predecessor). It stabilizes after 238 generations, leaving behind 2 blocks, 3 blinkers, 1 beehive, 1 boat, and 1 glider.
Commonness
According to Simon Ekström's census of small evolving patterns,[1] the Iwona active region is the 15th most common qualifying sequence, with 37747 occurrences, placing it between the blonk-tie and the U-turner.
Most predecessors tend to converge onto generation 5 of the pattern shown in the infobox.

Uses
In conduits
The Iwona active region is common and active enough to be used in conduits, and while conduits that accept the object are known, very little searching has been done.
In oscillators
There are 6 known oscillators that hassle the Iwona active region, all of which are listed on the Iwona active region hasslers page.
