Yet another merge device:

[ ]Q[ ] L R \/ \/ \ L Q R

However, this one does not easily extend to more than two inputs, unlike the ones used in the stack example program. Int-e (talk) 23:12, 5 March 2017 (UTC)

Can't you trivially put a third one coming straight through the upper Q? --Ørjan (talk) 00:53, 6 March 2017 (UTC)

Indeed you can, which means that you can stack several of these things on top of each other. So it does generalize in a fairly nice way to an arbitrary number of inputs after all, though I still think concentrating all inputs on a single beacon is the superior method.

[ | | | ] (in) 4 extensible 3 four way merge 2 \ 1 \ 4\ 3\ 2 Q/2 Q 1 [ ] (out)

Anoter design, this one uses just one pair of beacons and a mirror per input, and three beacons and a mirror for output. (Extending it may require moving the right Q further to the right, in which case the upper 1234... have to move up by the same distance) Int-e (talk) 20:21, 6 March 2017 (UTC)

The alternative merge device in the stack example can be extended as well. A more compact version:

→ 7 → 6 → 5 → 4 → 3 → 2 Z → 1 / → Q\Q Z X\/ \ Q/ 1 X 2 3 Y 4 \ /5 Y 6 7
