Emu

The term emu refers to Herschel loops that do not emit gliders. They are thus flightless, like the bird of the same name. This term was coined by David Buckingham. Emus have been constructed for period 52 and for periods 54 and higher (the first few are oscillator-assisted).

Emus as reflectors

Emus can be used to reflect gliders in a variety of ways. Adam P. Goucher (with help from Jason Summers) exploited this property to construct the first period-59 gun. Unfortunately, that method does not generalise to the remaining emu-only periods, since it uses a special p59 + 15n reaction based on David Buckingham's p44 oscillator.
