The prime-approximating strength of an EDO can be determined by the magnitude of Z(x). Since a higher |Z(x)| correlates to a stronger tuning, we would like to find a sequence with succesively larger |Z(x)| values satisfying some property. | |||

If we examine the increasingly larger peak values of |Z(x)|, we find they occur with values of x such that Z'(x) = 0 near to integers, so that there is a sequence of [[EDO|edo]]s | If we examine the increasingly larger peak values of |Z(x)|, we find they occur with values of x such that Z'(x) = 0 near to integers, so that there is a sequence of [[EDO|edo]]s | ||

We may define the ''strict zeta edos'' to be the edos that are in all four of the above lists. The list of strict zeta edos begins {{EDOs|2, 5, 7, 12, 19, 31, 53, 270, 1395, 1578, 8539, 14348, 58973}}... . | We may define the ''strict zeta edos'' to be the edos that are in all four of the above lists.

The following list of edos are not determined by successively large measured values, they are edos that purely satisfies some property relating to zeta peaks instead. | |||
