    (university of el oued/جامعة الوادي, 2021-05-01) Abdulganiy, R. I; Akinfenwa, O. A; Osunkayode, A. K; Okunuga, S.A
    This paper presents a higher order, block implicit, four step method with trigonometric coefficients constructed via multistep collocation technique. The stability properties of the method are discussed. Numerical results obtained disclose that the new method is suitable for the integration of second order nonlinear periodic problems.
