SPLITTING OF THE CHARACTERISTIC POLYNOMIAL (CP) USING A COMPUTATIONALTECHNIQUE TO OBTAIN THE FACTORS OF THE MIRROR PLANE AND 2-FOLD, 3-FOLD, AND N-FOLD SYMMETRICAL GRAPH

All possible quadratic factors from the characteristic polynomial are generated. Selective extraction of the factors are smoothly achieved. Factors of the mirror plane and two-, three-, and n-fold rotationally symmetric graphs are obtained without using any rule for the fragmenta tion pattern. The relationship among the irreducible representations o f the two-, three-, and n-fold operators are established through our c omputer program. (C) 1995 John Wiley & Sons, Inc.
