A Hadamard matrix is an optimal square arrangement of 1's and -1's. The optimality property of such matrices make them very convenient for coding purposes. Orthogonal designs are objects which include Hadamard matrices. An old problem predicts the existence of Hadamard matrices subject to a simple restriction on the size of the matrices. There are many problems related to orthogonal designs whose solution may lead to a resolution of this prediction.

阿达玛矩阵是1‘S和-1’S的最优平方排列，这种矩阵的最优性使它们在编码时非常方便。正交设计是包含Hadamard矩阵的对象。一个老问题是对Hadamard矩阵的大小有一个简单的限制来预测是否存在Hadamard矩阵。有许多与正交设计有关的问题，其解决方案可能会导致该预测的解决。
