同构数 正整数n若是它平方数的尾部，则称n为同构数。例如，6是其平方数36的尾部，76是其平方数5776的尾部，6与76都是同构数。376*376＝141376，所以376也是-Descr iption isomorphism few positive integer n, if the square of the number of its tail, then n is the number of isomorphism. For example, the square of the number 6 is the tail of 36, 76 is the number of 5776 square tail, 6 and 76 are isomorphic few. 376* 376 = 141,376, so 376 is also
