A nuclear reaction involves the hypothetical element X, which has an atomic number of 166, as a reactant. The 360X nuclide reacts with 5 neutrons yielding a nuclide of element Y along with, altogether, 2 beta particles, 5 neutrons, 3 alpha particles, 3 positrons, and 3 gamma rays. The number of neutrons in the nucleus of the resultant nuclide of Y would be:
