F166

F166 is a composite conduit, one of the original sixteen Herschel conduits, discovered by Paul Callahan in May 1997. It is composed of two elementary conduits, HFx107B followed by BFx59H. The F166 and Lx200 conduits are the two original dependent conduits (several more have since been discovered). After 166 ticks, it produces a Herschel at (49, 3) relative to the input. Its recovery time is 116 ticks. It can be made Spartan by replacing the snake with an eater 1 in one of two orientations. The output Herschel's first natural glider must be suppressed by an eater unless another dependent conduit follows the F166. The only known reflectors that could extract a signal from that glider, given the available space, are very expensive staged recovery devices using a bait object, so it makes much more sense to simply append another Herschel conduit if a glider is needed.

The pattern as shown in the infobox has a ghost Herschel marking the output location. It also starts with a three-tick predecessor of a Herschel, because the initial transparent catalyst block in this or any dependent conduit prevents the actual Herschel stage from forming. A second copy of the conduit is included in the pattern, below the working copy, to show the correct input Herschel location. Use this second copy as a guide for appending an F166 conduit to a previous Herschel conduit, but be sure to remove the Herschel after the two conduits are aligned correctly.
