Abstract
Perfect-fluid, diagonal G(2) spacetimes admitting a (proper) inheritin g conformal Killing vector (ICKV) are studied. A result which specifie s the possible form of an ICKV (under certain physical conditions) in such a spacetime is proven, and then used to determine all (physically admissible) diagonal G(2) perfect-fluid ICKV spacetimes. In particula r, all such spacetimes in which the perfect fluid satisfies a barotrop ic equation of state, mu > 0, mu + p not equal 0, and in which the ICK V is proper, are explicitly found.
