226/225 is a 2.3.5.113 subgroup comma measuring 7.68 cents. It is the amount by which the octave-reduced 113th harmonic (113/64) exceeds the classic augmented sixth of 225/128, and differs from the marvel comma (225/224) by 50625/50624 (S225, ~0.0342¢). It is the parent comma for the reversed marvel temperaments.
Temperaments
In the 2.3.5.113 subgroup, tempering out this comma results in the reversed marvel temperament. By substituting the 7th harmonic out for the 113th harmonic in the marvel temperament, it results in sharper 3rd and 5th harmonics, rather than flatter.
