The simplest possible dekany, comprised of two-combination sum products of the first 5 odd numbers. This creates a scale of 1 9/8 7/6 5/4 21/16 35/24 3/2 5/3 7/4 15/8 2/1, with steps of 9/8 28/27 15/14 21/20 10/9 36/35 10/9 21/20 15/14 16/15. Since every step is a quartertone or larger, it can be mapped unambiguously to a standard 12-tone keyboard.
