In this paper we derive the analytical formulas of the number of spin-I states (denoted as D-I) for three identical particles, in a unified form for both fermions and bosons. This is done by using (n) over bar virtual bosons with spin 3/2, where (n) over bar equals 2j - 2 if one studies fermions in a single-j shell or 2l if one studies bosons with spin l. We first obtain a reduction rule from U(4) to O(3) for such virtual bosons and thereby derive the formulas of D-I. The formulas thus obtained are proved to be consistent with previous empirical formulas.
