The relationship of all bit channels with N=29. a Black dots indicate that the relationship is determined from the two POs whereas white dots indicate that the relationship cannot be determined from the two POs. bThe underlying channel is AWGN with a SNR of 1 dB. On top of the black dots, the red dots indicate the additional intrinsic relationships obtained from the GPO
