    In this article are studied spectral properties of differential operators of the sixth order with delayed argument. It is supposed that coefficients of the operator are summable functions on a segment. 36 kinds of boundary conditions are simultaneously studied by this method. The asymptotics of the eigenvalues of this differential operator is also calculated.
