If you use a finger down as 0 and a finger up as 1, it's possible to=20
count to 1023 on your fingers.....
I have never gone that far, but (seriously) I routinely count to 31 on
one hand...
I have never managed to use ternary or symmetric ternary (place valeus of
-1, 0, 1) on my fingers, for all 3 states of each finger seem easily
possible. Nor have I ever managed to get the base -2 sequeence (it
starts 00000 00001 00110 00111 00100...) flowing nicely on my fingers.
