Group number limit

Hi, Steve,

I used the fullerene C60 to represent protein/nanoparticle in my simulation. It means one protein 60 particles. I defined these 60 particles as a group.
But the group number is limited to 32. The reson i use C60 as a protein is that i need a kind of protein/nanoparticle is charged into some different patches.
If I want to put more groups into my simulation, what should i do?? Any suggestion to this problem is
appreciated. Thanks!

Best regards

You don't say why you need each C60 in a group, but you
probably don't. You can make each one a different molecule,
and there is no limit to the # of molecules.
