Generating 4 elements equiatomic cylinders with LAMMPS

I need to make a cylinder of certain dimension containing 4 elements with a certain atomic ratio. How can I generate this using the inbuilt crystal structure generation algorithm in LAMMPS?
Will using Atomsk to generate the structure result a same result?

create the system with all atoms of one type and then use the “set type/fraction” command to change atom types as needed. make certain, that you use a different random seed for each call.
