In the article, Quantum Theory Derived from Logic, a logical expression was derived for n parallel paths of m steps each. This is equation [7] shown again below.

 

(q0 qn) = ni1,i2,i3,i4...im=0  (q0 qi1)(qi1 qi2)(qi2 qi3)(qi3 qi4)...(qim qn).

 

To gain some confidence that this expression is true, you can cut and paste the text into this truth-table generator. This is an expression for when n=4 and m=3. Altogether there are (n+1)m=53=125 different terms of 4 implications each.
