Huh, yes, you certainly can't do that with the old R suppression, though it puts the output B in the same place:

`x = 75, y = 36, rule = LifeHistory`

G21 is wide enough to allow Snarks or semi-Snarks to bounce the output gliders around easily, once they get to where they're going. Here's a reasonably compact 2D Herschel transceiver, for example:

`x = 172, y = 53, rule = LifeHistory`

This is pretty much just a curiosity nowadays -- might as well just use a syringe if you're stuck with non-Spartan catalysts anyway. But it might be useful to pair this G21 converter with other circuits that need two gliders for activation.
