The only thing I can come up with, is to have 2 differentials. The first
one (Diff. A) splits input 1 into outputs labeled 2 and 3. Item 2 connects
to a 2:1 gear reducer and goes to finger i). Item 3 goes to Diff. B's input
(item 4) and it's outputs, 5 and 6 go to fingers ii) and iii).
I *think* that would do it.
