1-3-5-7 by 21/16 bihexany

The simplest possible Hexany, offset by a harmonic fourth. This creates a scale of 1 35/32 147/128 7/6 5/4 21/16 35/24 49/32 105/64 5/3 7/4 245/128 2/1, with steps of 35/32 21/20 64/63 15/14 21/20 10/9 21/20 15/14 64/63 21/20 35/32 256/245. This does not have a 3/2 above the root, but does have 6 other perfect fifths, plus several wolf ones of various flavours on top of that, giving you numerous good chords to choose from, although the multiple 64/63's make it somewhat suboptimal melodically.
