With the help of generating solutions, we formed a basis for the existence of periodic orbits, then an analytical approach given by Hassan et al. [1], was applied to our model of equilateral triangular configuration. It is found that in general solution also; the character of periodic orbits is conserved. For verification of the existence of periodic orbits, we have applied the criterion of Duboshin [2] and found satisfied. %K Autonomous Four-Body Problem %K CR4BP %K Triaxial Rigid Body %K Regularization %K Generating and General Solution %K Periodicity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=77855
