1-3-7-13 stellated hexany
A 13-odd-limit stellated Hexany. This creates a scale of 1 273/256 39/32 21/16 91/64 3/2 13/8 7/4 2/1, with steps of 273/256 8/7 14/13 13/12 96/91 13/12 14/13 8/7. While it only adds two notes to the base hexany, in this case they are in exactly the right place to close the large gap it has, making an 8 note scale with 4 perfect fifths, each with at least one usable third, where every note is melodically effective that is quite easy to compose pleasant sounding music in despite the lack of factors of 5.
