| Abstract: | In low symmetry system, eight-fold multiple solution is an extreme case of multiple solutions on the positions of light atoms caused by the special arrangement of a single set of equivalent heavy atoms. This extreme case occured in the determination of the crystal structure of TIP.In this paper, the principle and practical procedure of solving this problem are given in detail. |
