[B] NO appears to be the answer from what I can find, though it probably has been somewhere somewhen.
[R] NO.

If you were standing in front of Raak and Chalky, one of whom always tells the truth and the other of whom always lies, and both know the AOTC, and all of you know the foregoing but you do not know which one is the truth teller, and you were to ask Raak "if you asked Chalky if the AOTC begins with the letter P, is it the case that she wouldn't not say 'No'?", is it the case that he wouldn't not say yes?

[CdM] YES. (I hope I've figured that out correctly!)
