I had an interesting find and a 'brown trousers' moment when I dropped into this system whilst looking for Black Holes on the way to Colonia 
There were actually FOUR Neutron Stars comprising the system.
Two of the NS were very close and quite close to the main NSD entry point. When there is another star close by, the NS seems to have a much more active plume. When that 'other star' is two more NS then navigating close to tag each (as one does) was interesting
A bit more evidence.
Not sure how rare this is, but it a definite first for me ...
