1605632/1594323 tempering

This the no-fives comma of hemififths; 2^15 3^(-13) 7^2. The
difference between the TOP tuning for this and for hemififths is a
negligable < 0.05 cents for 2, 3, and 7, and as a {2,3,7}-linear
temperament it's pretty well identifiable as hemififths. Since Michael
Harrison loves 3, likes 7, and seems to be willing to live without 5,
tempering 24 notes to hemififths seems like a plausible tuning method
for Harrison style music if one can live with fifths a cent sharp.
