It is the unique [[even-regular]] scale with this step signature (since the even-regular scale with a given step signature is always unique if it exists). | ||

Each generator is a 3-step supermajor second (L + m + s), interpreted as 8/7, and the offset is an 8-step interval. The fifth is 9 steps and is a stack of three 8/7 generators. When you temper out [[1029/1024]], this fifth is interpreted as [[3/2]]. | ||

[[Portent]] is the temperament 11-lim[1029/1024, 385/384], and interprets the 8-step interval as an [[Interseptimal interval|ultrafourth]] [[48/35]] or [[11/8]]. This is the interpretation originally found by groundfault. | |||

In this temperament, the 8-step offset is ~23/16 tempered together with 10/7 by tempering out 161/160. | |||

(However, Inthar recommends interpreting the scale in 2.3.7.13.17.23 for higher accuracy, interpreting the ~5/4 as ~64/51 and not as ~5/4.) | |||
Penslen in this temperament is represented by [[46edo]]'s 5:3:1 and [[67edo]]'s 7:4:2 tunings. | |||
