Pentadecathlon.png
Pentadecathlon is a period 15 oscillator that was found in 1970 by John Conway while tracking the history of short rows of cells (see one cell thick pattern). Indeed, 10 cells placed in a row quickly evolve into this object, which is the most natural oscillator of period greater than 3. In fact, it is the fifth or sixth most common oscillator overall, being about as frequent as the clock, but much less frequent than the blinker, toad, beacon or pulsar. It is the only known oscillator that is a polyomino in more than one phase (besides the blinker).

Did you know...

  • ...that the French kiss remained without a glider synthesis until 2013?
  • ... that Adam P. Goucher's distributed Catagolue soup-search project, started in February 2015, has already tested more random soups than any previous such project, and has contributed to the reduction of many glider construction recipes?
  • ... that any glider-constructible Life pattern can be constructed with a fixed maximum number of gliders N, probably less than 1000? It's only necessary to construct a sliding-block decoder, which self-destructs after converting the position of a far-distant block into a slow-salvo recipe that constructs the required pattern.
  • ... that Copperhead is not only the first c/10 orthogonal spaceship ever found, but also remarkably compact for a pattern not discovered until 2016?
  • ...that the largest interesting pattern constructed, the caterpillar, contains over 11 million cells?
  • ...that the Gosper glider gun was the first pattern to be discovered that exhibits infinite growth?
  • ...that the block-laying switch engine and the glider-producing switch engine 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?
