The id attribute is the atom-ID of the atom which owns the rigid body, which is assigned by the fix rigid/small command.. The mol attribute is the molecule ID of the rigid body. It should be the molecule ID which all of the atoms in the body belong to, since that is how the fix rigid/small …

The only difference is that the rigid and rigid/small styles use an integration technique based on Richardson iterations. The rigid/nve style uses the methods described in the paper by Miller, which are thought to provide better energy conservation than an iterative approach.
