Dear all
There is a box which has 60000 gold atoms with fcc crystal structure 
Now I want to divide it in to groups which each group has 8 atoms then I should calculate interactive forces between them 
Is there any command for it ?
I have tried group command but lammps accept just 32 groups
Thanks for your help
