Snacker is a period-9 oscillator consisting of a pentadecathlon hassled by four eater 1s, found by Mark Niemiec in 1972.[1][2]
The snacker produces domino sparks, which can be used for a p36 toad hassler. In other cases they may be rather inaccessible due to the eaters. By putting more pentadecathlons, the snacker is extensible as shown below, whose spark is more accessible. This leads to the first period-18 oscillator, 117P18. Stronger domino sparkers are also found, for example 50p9 and 104p9
This oscillator first appeared semi-naturally in the form stabilized by fourteeners instead of eater 1s in March 2016.[3]
| Additional pentadecathlons can be added to extend snacker. The alternate stabilization on the right was found by Dean Hickerson in April 1998. (click above to open LifeViewer) RLE: here Plaintext: here |
