Islands Ngc

Does NGC 3621 belong to any group of galaxies?

I know it doesn’t belong to the Local Group, but that’s as far as I was able to figure out on line. If it does, anyone know of a galaxy that doesn’t really belong to any group a galaxies, truly an island universe so to speak?

It does not appear (from current observations) to be gravitationally linked to any major galaxies.
