讨论了n阶完全四角问题和n阶不全四角问题是否有解以及解是否唯一 ,得到了如下结果 :3阶完全四角问题有唯一解 ;n(n >3 )阶完全四角问题无解 ;给出了n阶不全四角问题的公式解 ,便于计算机实现 ;而且偶数阶不全四角问题的解不唯一。
A discussion is made of the n-order complete four angles problem, whether the n-order incomplete four angles problem has a solution and whether the solution, if there is any, is unique. The following results are derived: the 3-order complete four angles problem has one and the only one solution and n (n>3)-order complete four angles problem has no solution; in addition, the formula solution for n-order incomplete four angles problem is offered to be computerized, and even-number-order incomplete four angles problem has at least 2 solutions.
