How about:
Define $\phi(i,j) \equiv f_i(W1_{j}W2_{j}W3_{j}$,
\begin{align}
\phi(1,n) =W1_{n}' W2_{n}' W3_{n}' & \stackrel{S_{1}}{\longrightarrow} \phi(1,n+1)
= (W1_{n+1}' W2_{n+1}' W3_{n+1}') \\
\phi(2,n) =W1_{n}' W2_{n}' W3_{n}' & \stackrel{S_{2}}{\longrightarrow} \phi(1,n+1)
= (W1_{n+1}'' W2_{n+1}'' W3_{n+1}'') \\
\phi(3,n) =W1_{n}' W2_{n}' W3_{n}' & \stackrel{S_{3}}{\longrightarrow} \phi(1,n+1)
= (W1_{n+1}''' W2_{n+1}''' W3_{n+1}''')
\end{align} |
