1-9-11-15 hexany
An 11-limit Hexany. This creates a scale of 1 55/48 11/9 11/8 5/3 15/8 2/1, with steps of 55/48 16/15 9/8 40/33 9/8 16/15. This is two clusters of surprisingly familiar smaller steps separated by more xenharmonic larger steps. Since even the smallest step is larger than a 12edo semitone but they still vary in size by a ratio of over 3:1, this is a very melodically effective hexany, but does not contain any familiar chords to root upon.
