Lx73 is a periodic elementary conduit. After 73 ticks, it produces an inverted Herschel turned 90 degrees counterclockwise at (12, 20) relative to the input. The form shown in the infobox has a recovery time of 70 ticks; without the block-suppressing eater 1 and the eater 5 that eats the output's first natural glider, the recovery time increases to 120 ticks.
The Herschel+domino reaction was found no later than 1991 — about the same time some p8 R64 conduits were discovered — when Dave Buckingham constructed two p8 versions of Lx73, one of which uses a figure eight and the other one two blockers.[1] The second variant releases an extra glider to the southeast, enabling the construction of gunstar 2.

In May 2007, Scot Ellison found a smaller version of the heavyweight volcano for the conduit, as shown in the infobox. It has better clearance in the north, allowing the usual block-eating eater 1 in most elementary H-to-X conduits.[2] For comparison an older, bulkier p5 variant is employed in the period-435 glider gun.
In the patterns shown above, ghost Herschels mark the output Herschels' locations.
