1-3-5-121 hexany
An 11-limit Hexany, comprised of three simple numbers and one much larger one. This creates a scale of 1 5/4 121/96 605/384 5/3 121/64 2/1, with steps of 5/4 121/120 5/4 128/121 363/320 128/121. This has the same structure as the 1-3-5-15 hexany, but with half the notes raised by 121/120, which means they are melodically identical but you can exploit the beating effects produced by combining 5/4 and 121/96, making this one more versatile overall.
