| Eater 1 (or fishhook or simply eater) was the first discovered eater. Its ability to eat various objects was discovered by Bill Gosper in 1971. It is the smallest still life that is neither radially symmetric nor symmetric through a line, and it is the thirteenth most common still life, being less common than mango but more common than long barge.
It only takes four generations to recover from being hit by a glider, making it the fastest-recovering glider eater, and it is also the smallest glider eater. As such, it appears as a stabilizer at the corner of dozens of oscillators including 36P22, buckaroo, P54 shuttle, pentoad, pre-pulsar shuttle 47, and snacker.
| The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:
Did you know...
- ...that the block-laying switch engine and the glider-producing switch engine (and various combinations of two switch engines) are the only two infinitely-growing patterns that are known to have ever occurred naturally from a nonsymmetric random starting configuration?
- ...that oscillators are known that oscillate at all periods other than 19, 23, 34, 38 and 41?
- ...that the pentadecathlon and the blinker are the only known oscillators that are polyominos in more than one phase?
- ...that it is impossible for a period 3 oscillator to be a phoenix?
- ...that the methuselah with the longest known lifespan, 40514M, lasts for over 40,000 generations before stabilizing? The second-place holder, Fred, runs for over 35,000 ticks.
- ...that replicators with quadratic population growth are known to exist in Conway's Game of Life, but none have yet been found?
- ...that the first known period 37 and 51 oscillators were found in 2009?
- ...that a pattern whose population grows without bound but does not tend to infinity is known as a sawtooth?
- ...that there are over 6.5 million distinct strict still lifes with 24 or fewer cells?
- ...that some infinitely-growing patterns can be constructed with as few as three gliders?
