Sensi[27] is a MOS containing the 7-limit diamond. Detempering it
gives the following 27-note JI scale containing the diamond:
! sensidia.scl
Detempered Sensi[27]; contains 7-limit diamond

The scale is not as regular as one might hope, having intervals
ranging from 225/224 down to 28/27. It has six otonal and six utonal
tetrads, and the subscale consisting only of those tetrads has 21
notes, also containins the diamond, and also has superparticular scale
steps:
! sentdia.scl
Consists of the tetrads of detempered Sensi[27] = sensidia.scl

This has six o and six u tetrads, and three each complete quintads.
One more of each kind if you marvel temper. Scale steps range from
50/49 down to 21/20, with all superparticular step sizes.
