37/36, or the 31-limit Wyschnegradsky ~quartertone, is a 2.3.37 subgroup comma. It is the amount by which 37/32 (the 37th harmonic) exceeds the Pythagorean (major) whole tone of 9/8. It is significant in Helmholtz-Ellis notation as the formal comma to translate a Pythagorean interval to a nearby 37-limit (prefix???) interval.
