...We find that the result from comparing the oriented area of planes defined by these vectors between multipole pairs 2 <= l1 != l2 <= 8 is inconsistent with the isotropic Gaussian hypothesis at the 98.8% level for the ILC map and at 99.6% level for the cleaned map of Tegmark et al. A particular correlation is suggested between the l=3 and l=8 multipoles, as well as several other pairs. This effect is entirely different from the now familiar planarity and alignment of the quadrupole and octupole: while the aforementioned is fairly unlikely, the multipole vectors indicate correlations not expected in Gaussian random skies that make them unusually likely. ...

If it's not topology, it's something else weird (politically incorrect ;) that happened on near-horizon scales...
