86edo

g_

86 is an edo whose use is generally confined to my approach, and is up there with 74edo as one of my default large edos. It's a straddle edo good for Interarch and my quartertone theory. Alongside being double the already respectable 43edo, this makes it my favorite edo at the time of writing.

SS

86edo may be seen as a system introducing neutral intervals to 43edo

22&86bde is very good at generating 86edo Archy pental blackdye and its related quasi-Porcupine. It's similar to Comic temperament. See Straddle cluster temperaments#Quartertone. 3sA Aeolian and additional italicized notes of 1sRM Dorian are highlighted.
