Abstract：
The branching rules for group chain U(N)SP(N)O(3) of the irreducible representations [2a1b] of U(N) are discussed in some detail. Simple analytical recurrent formulae of these branching rules for above group chain are obtained. They are very efficient to simplify the calculations of Fractional Parentage Coefficients. This method can be used to find the branching rules for the group cLam U(N)O(N)O(3) too.
