摘要
通过构造幻方积最小的三阶乘积幻方给出了三阶乘积幻方可构造的一个充分必要条件,并完全确定了所有元素为不同正整数的三阶乘积幻方的结构.
In this note, via constructing multiplicative magic squares of order three with the smallest product constant, we get a necessary and sufficient condition under which multiplica- rive magic squares of order three can be constructed. Then we find all multiplicative magic squares of order three with distinct positive integer elements can be completely determined.
