37ED4 is an equal tuning which divides the 4/1 double octave into 37 steps of approximately 64.865¢. As an ED4 system, it is equivalent to taking every other tone of 37edo. All the intervals of 37ED4 are thus the same as or an octave away from a corresponding interval in 37edo.
65cET is a slightly stretched version of 37ED4, in which the 37th degree is 5¢ sharp of 4/1.
