Solutions of Einstein's field equations with cosmical constant are derived for a flat axially-symmetrical uniform model universe containing only dustlike matter. They are classified by means of the transverse deceleration parameter q0 and the transverse density parameter Oo. The age of the universe is computed and illustrated by contours on the (q0, q0) plane. Key words: Age of the universe; Anisotropic universe; Classification of models; Cosmical constant.
