If we want to find the second-best edos ranked by zeta peaks, then given a full list of zeta peaks, we can remove the successively higher peaks to get another sequence of succesively higher peaks, which correspond to edos called '''Parker edos'''.
If we want to find the second-best edos ranked by zeta peaks, then given a full list of zeta peaks, we can remove the successively higher peaks to get another sequence of succesively higher peaks, which correspond to edos called '''2-ary peak edos''': defined as non-zeta-peak edos with a higher zeta peak than any smaller non-zeta-peak edo.  


Named after the Parker square in recreational mathematics, ''Parker edos'' may be defined as non-zeta-peak edos with a higher zeta peak than any smaller non-zeta-peak edo. This list can be used finding an alternative to any given zeta peak edo of similar size and still-okay accuracy, but with different regular temperament properties (e.g. 9 as alternative to 10, 17 as alternative to 19).

We can then remove those secondary peaks again to get '''tertiary-peak edos''': non-zeta-peak edos with a higher zeta peak than any smaller non-zeta-peak ''or'' Parker edo.
We can then remove those secondary peaks again to get '''3-ary peak edos''': non-zeta-peak edos with a higher zeta peak than any smaller edo that is neither a zeta peak nor a 2-ary peak.

We can do this as many times as we want, resulting in '''''k''-ary-peak edos'''. The ordinary peak edos are 1-ary (primary)-peak edos, Parker edos are 2-ary (secondary)-peak edos, and so on.
We can repeat this process as many times as we want, resulting in '''''k''-ary-peak edos'''. The ordinary peak edos are 1-ary peak edos, then there are 2-ary peak edos, 3-ary peak edos, and so on. However keep in mind that the higher ''k'' gets, the less meaningful the peaks will get, especially for smaller edos (less than about 100).
