| 摘 要： | 从1890年法国G·Pfeffermann发明了第一个平方幻方至今,幻方得到了空前发展。我国幻方爱好者积极开展平方幻方构造探索,涌现出了一大批著名专家,把幻方研究向前大大地推进了。3m、4m、5m、7m阶平方幻方中,构造难度最大的是3m阶平方幻方,苏茂挺、高治源利用九宫图的布局和已知的平方幻方合成,成功构造了30阶、33阶、36阶、39阶、42阶、51阶、54阶、57阶平方幻方。

| Abstract: | Since the first bimagic squares invented by G.Pfeffermann in 1890 so far,the magicsquare has god unparalleled development.Magic square amateurs in our country have actively fore,thus pushing the study of magic squares forward greatly.In 3m-order,4m-order,5m-order and 7m-order bimagic squares,the maximal structural degree of difficulty is 3m order bimagic square.By making use of the placement of magic squares and the known bimagic square composition,SU Maoting and GAO Zhiyuan have successfully structured 30-order,33-order,39-order,42-order,51-order,54-order,57-order bimagic squares. |
