On a `mysterious' case of a quadratic hamiltonian.
S. Sakovich

TWe show that one of the five cases of a quadratic Hamiltonian, which were recently selected by Sokolov and Wolf who used the Kovalevskaya-Lyapunov test, fails to pass the Painleve test for integrability.
Key words: Hamiltonian system; nonintegrability; singularity analysis
