- Not to be confused with Fx153.
Fx158 is an elementary conduit, one of the original sixteen Herschel conduits, discovered by Dave Buckingham on July 7, 1996. After 158 ticks, it produces an inverted Herschel at (27, -5) relative to the input. In the pattern shown in the infobox, a ghost Herschel marks the output location.
It is the only known small conduit that does not produce its output Herschel via the usual Herschel great-grandparent, so it cannot be followed by a dependent conduit that relies on the usual evolutionary sequence (such as R49, NW-2T16, or a conduit that uses the transparent block reaction). Attempting to put a block there will just cause the block to be eaten. On the other hand, when followed by an independent conduit, the first natural glider has to travel back and be absorbed by the large welded eater, leading to a recovery time of 176 ticks. However, when followed by the "pseudo-stable" HRx74B conduit,[1] it can be overclocked to 90 ticks as it is a dependant conduit where the Herschel interacts with the block at T = 9.
By suppressing the reaction early, it is possible to release the temporary glider labelled NE2T56.[2]
