Meaning of R-pentomino | Babel Free

Definitions

1. A particular five-square polyomino.
2. The methuselah based on this polyomino that, in Conway's Game of Life, has a lifespan of 1,103 generations.

Examples

“I came up with an implementation of an algorithm on my Sparcstation 1 that does all 1103 generations of the R-pentomino, including the gliders, in 1.3 seconds (no display), and runs o.....o. ..o...o. ..o..o.o .o.o.... (a pattern by Wainright recommended to me by Gosper) out to 10,000 generations in 45 seconds (again, without display).”

“I've finisher debugging the code, and it works -- that is to say, its final configuration for the R-pentomino is the same as the one in my books. (It's my guess that the R-p will find any bug in any life program, no matter how obscure.)”

“This explosive collision is "perturbed" by the permanent parts of the reflector so that at generation 242, the destroyed block is restored, a glider is released in the reverse direction, an r-pentomino is produced some distance from the stage, and a beehive is left in an awkward position close to the block.”
