Pentadecathlon on snacker

Pentadecathlon on snacker is a period-45 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 non-trivial, because it has two cells that oscillate at the full period. It was the first non-trivial 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 non-trivial period 45 oscillator, after pentadecathlon on thumb 1 with 48 cells.
