L141 is a Spartan elementary conduit found by Lucy D'Agostino on April 30, 2024, based on a partial conduit found by AlbertArmStain. It consists of three eater 1s, a block, a boat and a tub.

It is notable because, as Dave Greene put it:

“ Useful new additions to this slsparse-compatible toolkit only come along very rarely. The new L141 is simple and cheap to build, and produces extra output gliders in all directions, including one at its outside corner equivalent to the very useful L156 conduit's corner output -- but then it produces its Herschel output in an odd number of ticks, and the Herschel is on a different square color.

We haven't had an elementary conduit that did that until now. For an arbitrary large self-constructing construction -- the RCT's optimized ECC, let's say, or the supporting mechanisms for the unidimensional spaceship, or a new self-constructing computer with a 2D stable memory storage mechanism -- I suspect that having L141 in the toolkit will cut a noticeable number of percentage points off of the total construction cost.

”

Despite the output intersecting with the input Herschel's second natural glider, L141 can still connect to conduits like Fx153 and HFx58B by substituting a transparent block for the first block-suppressing catalyst. The block is destroyed by the input Herschel's SNG, then replaced by the output Herschel's first natural block.
