For example, we have Δ_{3} = 0 1 0 2 1 0 1 and *E*_{3} = 0 2 1 2 0 2 1, if we underline the *a*’s and *b*’s to distinguish them from the φ’s and *ψ*’s; and

here *a*_{3}φ_{4} and *b*_{3}*ψ*_{4} are empty. Elements have been underlined for the next step.

Thus we can compute the delta sequences in memory as follows. Here *p*[*j*] = *j**π** _{n}* for 1 ≤
