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. In the pattern shown in the infobox, a ghost Herschel marks the output location.

Its recovery time is very slow, 271 ticks, because it relies on the output Herschel's first natural glider to clean up the input Herschel's first natural block (visible in the infobox starting at T=37). Most other conduits include an eater1 to suppress that block, but there's no room for a catalyst in that location in the Bx222.

The conduit produces an extra glider in the northwest, but that glider can only be released if the Herschel is suppressed or if staged recovery conduits are used, since most elementary H-to-X conduits require an eater 1 to eat the first natural block of the Herschel. These and/or other early catalysts in conduits attached to the Bx222 would be damaged if the NW glider is allowed to escape. Therefore an eater 5 variant is generally required, which prevents the Bx222 from being considered Spartan.

The specific eater 5 variant shown in the infobox allows for an Fx77 and similar conduits to be appended using a simple weld—a standard eater 5 won't fit as well. F117 and similar conduits can also be appended, but only by replacing the eater 5 variant with a 7x9 eater or something similar, and using a more complicated weld.
