BTW, I had overlooked this so far. This is a special point that fouridx 
addresses.

Very good! However, according to www.ctan.org/pkg/fouridx this just is made 
to improve \sideset from amsmath, in the present case 
$\sideset{^x}{}{\operatorname{N}}$ suffices. For comparison: 
$\sideset{^x}{^x}{\operatorname{N}}$). $^x\mathrm{N}^x$ also has the 
symmetry, but the superscripts are lower than with `N' as an operator. I 
was about to suggest $^x\!\operatorname{N}^x$ which repairs horizontal 
spacing, but the left superscript is lower than the right one ...

Cheers,

     Uwe.
