Since logarithm of 2 in base 10 is equal to 0.30102999..., one step of 30103edo comes exceptionally close to being one step of an otherwise perfectly decimal tuning system, [[100000ed10]], similar to heptameride being one step of [[301edo]] and savart being one step of [[1000ed10]]. It was named '''jot''' by Augustus de Morgan in 1864. | |||
Any integer [[Gallery of arithmetic pitch sequences#APS of jots|arithmetic pitch sequence of ''n'' jots]] is technically a subset of 30103edo, since it is every ''n''th step of 30103edo. | |||
