The three essentially undecimal marvel hexads are particularly interesting. One is palindromic: 1-9/8-5/4-7/5-8/5-7/4 with steps 9/8-10/9-9/8-8/7-12/11-8/7. The two others are an inversive pair: 1-9/8-5/4-11/8-8/5-7/4 with steps 9/8-10/9-11/10-7/6-12/11-8/7 and 1-8/7-5/4-16/11-8/5-16/9 with steps 8/7-12/11-7/6-11/10-10/9-9/8. The latter two have steps which are permutations of the steps of the 11-limit JI hexads. | The three essentially undecimal marvel hexads are particularly interesting.
