These are rank-3 temperaments tempering out the [[semicanousma]], 14641/14580 = {{monzo|-2, -6, -1, 0, 4}}, but we can begin by looking at the rank-4 temperament.  
{{Technical data page}}
The '''semicathartismic clan''' of [[rank-3 temperament]]s [[tempering out|tempers out]] the [[semicathartisma]] ({{monzo|legend=1| -2 -6 -1 0 4 }}, [[ratio]]: 14641/14580).


Temperaments not discussed here include [[Hemimean family #Triglav|triglav]] and [[Canou family #Semicanou|semicanou]].  
For the rank-4 semicathartismic temperament, see [[Catalog of rank-4 temperaments #Semicathartismic (14641/14580)]].
