3-9-15-21 hexany

A quite composite 7-limit Hexany. This creates a scale of 1 7/6 5/4 35/24 5/3 7/4 2/1, with steps of 7/6 15/14 7/6 8/7 21/20 8/7. This is notable because it is the first hexany that is a direct duplicate of a simpler one, as all the notes having factors of three mean they cancel out, leaving it identical to the 1-3-5-7 hexany. However, it is important to note that their stellated hexanies are not identical, which means it is not completely redundant to catalog this separately.
