The ~~2100 equal division divides the octave into 2100 parts of precisely 4/7 cents (0.5714 cents) each. The~~ patent val tempers out 32805/32768 in the 5-limit and 2401/2400 in the 7-limit, and thereby provides an excellent tuning for 5-limit ~~schismatic aka~~ [[~~Schismatic_family~~|helmholtz]] temperament, and the 7-limit [[~~Schismatic_family#Sesquiquartififths|~~sesquiquartififths ~~temperament~~]]. As with any equal division of this size, it ~~supports~~ a number of possible meantone tunings, but ~~<~~2100 ~~3319 4876 5890|~~ is notable for being ~~nearly identical~~ to [[~~Quarter-comma_meantone|~~quarter-comma meantone]].
