L122 is an elementary stable Herschel conduit completed by Aidan F. Pierce in July 2020. After 122 ticks, it produces a Herschel turned 90 degrees counterclockwise at (3, -30) relative to the input. Its recovery time is 100 ticks. It is considered a dependent conduit because the input Herschel's first natural glider is not produced. In the pattern shown in the infobox, a ghost Herschel marks the output location.

The supported beehive catalyst works just as well in mirror image, but then the eater 4 leaves less space for the preceding Herschel conduit to fit. The beehive can be replaced by a tub while moving the eater 1 and eater 4 one cell upward for a smaller recovery time at the cost of slightly less clearance. An Fx77 conduit can precede the L122 if the aircraft carrier in the northwest catalyst is replaced by an eater 1.

The original form of this conduit was a periodic version using a heavyweight emulator, found by Tanner Jacobi in January 2016. This was followed in July 2020 by a compact p2 conduit using killer toads by Entity Valkyrie, with recovery time 90 instead of 100. This reduced the size of several guns in the reference glider gun collection.
