Trivially related lax pairs of the Sawada-Kotera equation

‎We show that a recently introduced Lax pair of the Sawada-Kotera equation is not a new one but is trivially related to the known old Lax pair‎. ‎Using the so-called trivial compositions of the old Lax pairs with a differentially constrained arbitrary operators‎, ‎we give some examples of trivial Lax pairs of KdV and Sawada-Kotera equations‎.
