16808edo is distinctly [[consistent]] and highly accurate through the 35-odd-limit, and can be used as a [[interval size measure|measure of interval size]] (the [[jinn]]) for most intervals which occur in practice. It is a very, very strong 31-limit division, and a [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak]], [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak integer]] and [[The Riemann zeta function and tuning #Zeta EDO lists|zeta integral edo]]. In the [[23-limit|23-]], [[29-limit|29-]] and [[31-limit]] it has the lowest [[Tenney-Euclidean temperament measures #TE simple badness|relative error]] up until [[148418edo|148418]]; in the 17- and 19-limit up until [[20203edo|20203]]; though in the 13-limit it is beaten out by smaller edos {{EDOs| 5585, 6079, 8269, 8539, 13112 and 14618 }}.
16808edo's step size is sometimes called a '''jinn''', a term proposed by [[Gene Ward Smith]]<ref>[https://www.huygens-fokker.org/docs/measures.html Stichting Huygens-Fokker: Logarithmic Interval Measures]</ref>, when used as an [[interval size unit]].
 
== Theory ==
16808edo is distinctly [[consistent]] and highly accurate through the 35-odd-limit, and its step size can be used as an [[interval size unit]] (the jinn) for most intervals which occur in practice. It is a very, very strong 31-limit division, and a [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak]], [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak integer]] and [[The Riemann zeta function and tuning #Zeta EDO lists|zeta integral edo]]. In the [[23-limit|23-]], [[29-limit|29-]] and [[31-limit]] it has the lowest [[Tenney-Euclidean temperament measures #TE simple badness|relative error]] up until [[148418edo|148418]]; in the 17- and 19-limit up until [[20203edo|20203]]; though in the 13-limit it is beaten out by smaller edos {{EDOs| 5585, 6079, 8269, 8539, 13112 and 14618 }}.


Among the enormous list of 31-limit commas it tempers out, the simplest are 43681/43680, 49011/49010, 52326/52325 and 53361/53360. In the 13-limit it tempers out 123201/123200 and 1990656/1990625; in the 17-limit 194481/194480 and 336141/336140; in the 19-limit 43681/43680, 89376/89375 and 104976/104975. Since 43681/43680 is both the simplest comma it tempers out and the limit is as low (in this context) as 19, it may be regarded as rather characteristic of 16808.

16808 has proper divisors 1, 2, 4, 8, 11, 22, 44, 88, 191, 382, 764, 1528, 2101, 4202 and 8404, among which [[22edo]] and [[764edo]] are particularly notable. One step of 22edo is 764 jinns, and one step of 764edo is 22 jinns.

== Intervals ==
Below the intervals of the 35-odd-limit [[tonality diamond]] are tabulated, with the sizes listed in both [[cent]]s and jinns. The worst error occurs for 33/25 and 50/33, which is less than 1/4 of a jinn off. The measure in jinns can be rounded to the next integer to find the corresponding [[degree]] of 16808edo.
