A 13-limit Bihexany. This creates a scale of 1 15/14 455/396 325/264 130/99 175/132 140/99 50/33 13/8 195/112 13/7 15/8, with steps of 15/14 637/594 15/14 16/15 105/104 16/15 15/14 429/400 15/14 16/15 105/104 16/15. This expands the base hexany out into a highly accurate detemper of 10edo without increasing the prime limit, with many of the composite ratios cancelling out to create simpler ones, making it the natural choice if you want to create a just intonation approximation of 10edo using a combination product set.
