Finally I manage to create stable version with no borders.

For example:
The R-pentomino is a methuselah that was found by John Conway in 1970.
It stabilize in generation 1103, by which time it has a population of 116 including 5 running away gliders. The glider it releases in generation 69, was the first glider ever observed.
