A 15-odd-limit dekany. This creates a scale of 1 33/32 11/10 21/16 11/8 7/5 3/2 7/4 15/8 77/40 2/1, with steps of 33/32 16/15 105/88 22/21 56/55 15/14 7/6 15/14 77/75 80/77. This is two clusters of close notes separated by large gaps, making it quite xenharmonic, but in a melodically interesting way, as even if it does not have any familiar chords, at least the steps are still large enough to be distinct and mappable without moving them more than 100 cents away on a standard keyboard.
