摘要
以ｎ＝３，４为基础，给出了（ｎ＋２）阶同心幻方外框上４（ｎ＋１）个元素的占位公式．据此即可逐步递推形成ｎ≥５的任意阶同心幻方．
The expressions of 4( n +1) elements on outer frame of the ( n +2)th order for concentric magic square are established on the basis of n =3,4. According to those expressions, we can obtain the n ≥5 arbitrary order for concentric magic square.
