In this paper, Sadhana (Sd) index of a pericondensed benzenoid graph consisting of three columns and having m, n, and k hexagons (counted column wise), in armchair position, is computed in a simple way under different cases. Case for two rows and for three rows (zig-zag position) has already been established. It is concluded that the results obtained are same for both zig-zag and armchair positions.
