5/4-9/8-15/14-7/6-15/14-15/14. It was considered by Mike Battaglia, who regards it as "trippy". Although the octave-reduced voicing for this chord is 1-5/4-7/5-3/2-7/4-15/8, a simpler and less compact voicing is 1-3/2-5/2-7/2-15/4-45/8, or 8:12:20:28:30:45. Other less compact voicings are also likely to be preferred, for instance 1-5/4-7/5-7/4-3-15/4, etc.
