How do i calculate number of possible transmission reciprocations?

If i have two gearwheels with 256 characters, each have a sign
encoded for every (edge/tooth?) using a keyed permutation, and between
them i have two transmission gears.

The set of transmission gears ranging from 3 tooths to 1024 tooths.
How do i calculate
A. Number of possible transmissions reciprocations
B. The total number of states the rig can produce?

I was thinking this is as a old crypto device where we connect a main
wheel with know characterset that is turned like a safe to write words
and sentences, the two keyed permutation wheels is then xor to give
the ciphertext. The keyed permutation is used to construct the two
encoded wheels, and a hash from key is used to select the two wheels
to interconnect them? Would it work?

256!^2*((1021*1020)/2) states?
