Create atoms

Hello Sir Akohlmey
May be my Question are bothered you every time… But i doing work on Active matter using lammps without supervision… so i found here a good platform for guideness …
My question is…
is it possible to create 144 particles on square lattice with a =3 and system size of Lx=36,Ly=36 with boundary conditions along x and y.
i read documentation again and again but still i have no success…

if possible then what ll be the procedure?
Thank you…

Sorry, but if you cannot make sense of the documentation for such a rather trivial task, then you you either need to find a suitable personal tutor or find a different research project/topic/area. An online forum is no replacement for proper training.

Thanks sir… I try to make it for me …
