== Slendi ==
Considered below are slithy, tridecatonic, slendi and dhaivatic, in the order of increasing [[badness]].  
Slendi may be described as the {{nowrap| 41 & 42 }} temperament. It has a generator of [[49/48]], seventeen of which give [[4/3]]. Its [[ploidacot]] is omega-17-cot.
 
The name was likely derived from ''slendro diesis'', one of the names for the interval 49/48.
