  The Noether symmetry issue for Horndeski Lagrangian has been studied. We have
been proven a series of theorems about the form of Noether conserved charge
(current) for irregular (not quadratic) dynamical systems. Special attentions
have been made on Horndeski Lagrangian. We have been proven that for Horndeski
Lagrangian always is possible to find a way to make symmetrization.
