A 13-odd-limit pentadekany. This creates a scale of 1 13/12 55/48 7/6 5/4 65/48 11/8 35/24 143/96 77/48 13/8 5/3 7/4 11/6 91/48 2/1, with steps of 13/12 55/52 56/55 15/14 13/12 66/65 35/33 143/140 14/13 78/77 40/39 21/20 22/21 91/88 96/91. This has five perfect fifths, plus several more imperfect ones, including a 12 cent flat one above the root, which gives it some familiar chords, but none of them connect to one-another via chains of fifths and there are many highly xenharmonic combinations of notes as well, which you are more likely to hit if you just play around randomly in this scale.
