38P7.2 is an unnamed period 7 oscillator discovered by Nicolay Beluchenko on February 17, 2009. It provides six sparks in generation 4 that are useful in creating non-trivial oscillators of higher periods such as snacker on 38P7.2. A variation of this oscillator can be created by displacing one half of the oscillator by two cells.
