An ordered phase with the generalized spin orientation of the Ising modelconsisting of ferro- (A) and antjferromagnetic (B) bond-mixttu'e is investigatedin detail on a triangular cactus tree in the case of J.= -J.=./(>0). The longand short range order-parameter are able to be defined clearly, arnd thus thesequantities, energy and spin-pair correlations are estimated at various temperaturesand bond-concentrations. At the transition temperature a jump itt the specificheat and a cusp in the uniform susceptibility are found. Some of calculated resultsare considerably good agreement with those obtained from Monte (Carlo simula-lions on a triangular lattice.
