Fore and back is about the thirty-eighth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than boat on spark coil and block on griddle, about as common as 21P2, and more common than trans-block on long hook eating tub and trans-beacon down on long hook. It is the most common billiard table oscillator.
In August, 2013 a 24-glider synthesis of this oscillator was found by Martin Grant, based on a soup, provided by Lewis Patterson. Several days later Mark Niemiec improved this result, having found a 20-glider synthesis.
