1-5-7-11-13-15 eikosany

A 15-odd-limit eikosany. This creates a scale of 1 143/140 33/32 15/14 11/10 33/28 39/32 143/112 13/10 11/8 39/28 165/112 3/2 11/7 13/8 195/112 143/80 13/7 15/8 429/224 2/1, with steps of 143/140 105/104 80/77 77/75 15/14 91/88 22/21 56/55 55/52 78/77 55/52 56/55 22/21 91/88 15/14 77/75 80/77 105/104 143/140 448/429. This does have 6 perfect fiths, and it is not impossible to construct stable chords in it, but it also has many clusters of notes that produce dissonance when played together, making it one of the more challenging eikosanies to work with so far.
