Hexatonic means six notes per octave, pentatonic five notes per octave, heptatonic (?) seven notes per octave and octatonic (?) right notes per octave in a scale.
There are not many useful hexatonic scales, mostly wholetone and tritone major triad pair (Petrushka chord). Other hexatonic scales are usually reduced heptatonic scales that miss one note.
