Remarks on: Ground state eigenvalue of the anharmonic potential x4+λx6 by high accuracy analytic functions, Pablo Martin, Daniel-Diaz-Almeida and Fernando Maass [Results Phys 18 (2020) 103291].

We believe high accuracy analytic function approach will no longer be useful in calculating the ground state energy of V(x)=x4-λx6 and similar Hamiltonians.
