F117 is a composite conduit, one of the original sixteen Herschel conduits, discovered by Dave Buckingham on July 5, 1996.^[1] It is made up of two elementary conduits, HFx58B and BFx59H. After 117 ticks, it produces a Herschel at (40, -6) relative to the input. Its recovery time is 63 ticks. It can be made Spartan by replacing the snake with an eater 1 in one of two orientations.

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