Abstract
We investigate the integrability of cosmic strings in Bianchi III spac etime using a symmetry analysis. The behaviour of the model is reduced to the solution of a single second order nonlinear differential equat ion. We show that this equation has a rich structure and admits an inf inite family of solutions. Our class of solutions extends special case s previously obtained by Tikekar and Patel [Gen. Relativ. Gravit. 24, 397 (1992)].
