The "ROP" phase transition of a triangular cactus tree composed of [sing spinswith bond-diluted antiferromagnetic interaction is considered. In the restrictedregion of the concentration of antiferromagnetic bonds between 0.771 and 0.478an ordered phase which is associated with the spin orientation of the ground stateis shown to be allowed. The temperature dependence of the order parameter,spin-pair-correlation and energy are also estimated. The specific heat exhibitsa smaller but more sharp peak than that in a dilute ferromagnet at the transitiontemperature T.. The susceptibility has a weak cusp at T.. The present results arecompared with the Monte Carlo simulations on a planer triangular lattice.
