Two copies of the simplest possible Hexany, offset by a large semitone. This creates a scale of 1 15/14 7/6 5/4 75/56 35/24 25/16 5/3 7/4 25/14 15/8 2/1, with steps of 15/14 49/45 15/14 15/14 49/45 15/14 16/15 21/20 50/49 21/20 16/15. This is the simplest of the three bihexanies derived from this hexany that has a single repeated note, resulting in an 11 note scale with a clear line of symmetry through the centre. While it does not have a fifth above the root, it does have 4 other perfect ones and 2 marvelous ones, giving you plenty of stable rooting places with simple consonant chords above them and only one interval that is mildly dubious melodically, making it one of the stronger ways of expanding out this hexany.
