Help with some questions about the ZBL form

[manbujin]

Hello！
I would like to ask you in what order I should prepare the ZBL table if the system I want to train has four elements, and the order in POSCAR is ABCD.
Is it in the order of A-A、A-B、A-C、A-D、B-B、B-C、B-D、C-C、C-D、D-D？
Thank you so much！

Suppose that A is type 0, B is 1, C is 2 and D is 3, then the order of columns in the tabulation file is
A-A、A-B、A-C、A-D、B-B、B-C、B-D、C-C、C-D、D-D
