Bx222 is a composite conduit, one of the original sixteen Herschel conduits, discovered by Paul Callahan in October 1998. It is made up of three elementary conduits, HF95P, PB68B and BFx59H. After 222 ticks, it produces a backward-traveling inverted Herschel at (6, -16) relative to the input. Its recovery time is 271 ticks
The eater 5 at the top can theoretically be removed to produce an extra glider, but in practice this greatly reduces the number of conduits that can be appended to the Bx222 because most conduits have an eater 1 in that position. Bx222 can be considered Spartan by the modern slsparse definition, assuming the high-clearance eater 5 is replaced by a standard tub-with-tail eater.
In the pattern shown in the infobox, a ghost Herschel marks the output location.
