Do you want the lattice to be infinite or do you just want it to look like it's 
infinite?  If you want an infinite lattice, you need to build it such that bonds 
can be formed across periodic boundaries, in conjunction with the .mdp keyword 
periodic_molecules set to "yes."  This is the approach many people take when 
simulating graphene sheets or CNT.  See the list archive for extensive discussions.
