Pentadecathlon on snacker is a period45 oscillator composed of a pentadecathlon and a snacker. Although it is composed of two oscillators of smaller periods (15 and 9 respectively), it is considered to be nontrivial, because it has two cells that oscillate at the full period. It was the first nontrivial period 45 oscillator to be discovered and was discovered sometime before August 1995. In terms of its 52 cells, it is the second smallest known nontrivial period 45 oscillator, after pentadecathlon on thumb 1 with 48 cells.
