The length of a maximum evenness scale's generator can be determined through a '''modular multiplicative inverse''' of the note amount and the tuning size<ref>https://individual.utoronto.ca/kalendis/leap/index.htm</ref>:

<math>ax \equiv 1 (\~~textbf{~~mod} N)</math>,

<math>ax \equiv 1 \mod N</math>,

where N is the period, and a is the note count. Therefore, a concoctic scale is defined for a given N:

<math>aa \equiv 1 (\~~textbf{~~mod} N)</math>,

<math>aa \equiv 1 \mod N</math>,

which simply becomes

<math>a^2 \equiv 1 (\~~textbf{~~mod}d N)</math>.

<math>a^2 \equiv 1 \mod N</math>.

Paraconcoctic scales are those, which in a pure sense are the octave inversions of one another. For example, a {7/10}'s generator is 3, and of {3/10} is 7. Since octave-inverting the MOS generator has no impact on the scale, paraconcoctic scales are identical to their usual counterparts. However, the difference is pronounced in keyboard making - in paraconcoctic scales, white keys' generator will be the amount of black keys and vice versa. The formula for such a scale is

<math>a^2 \equiv -1 (\~~textbf{~~mod}d N)</math>

<math>a^2 \equiv -1 \mod N<</math>
