D4-Complementability

Actually I am just trying to see why newer posts aren't showing up.

"Hexachords that map to their complement under D4 only map to T3 or T9,
unless they are chords of limited transposition"

Chords of limited transposition

A maps under T1, T3, T5... (T3, T7, T11 and T1, T5, T9 alternating)
P also maps under T3, T9
U maps under T1, T3, T5...
I maps under S3 only

I have chosen the generator (1,7)(3,9)(5,11) for D4. This is defined
as T0.

Post!
