Snacker is a pentadecathlon with eater 1 stabilizers that force it into a lower period (from 15 to 9). It was found by Mark Niemiec in 1972.[1] The stabilizers make the dominospark largely inaccessible, but the snacker is extensible as shown below and so a more accessible period 9 domino spark can be obtained – this is exactly the method that was used to create the first period 18 oscillator, 117P18. A more accessible domino spark can also be obtained using a different oscillator shown below.
Additional pentadecathlons can be added to extend snacker. The alternate stabilization on the right was found by Dean Hickerson in April 1998. Download RLE:click here
