列表的置换，其中每个元素都是int的数组

我有一个90的列表，列表中的每个元素都是一个600的int数组。现在我想在这个列表上执行排列（而不是在int数组上），也就是说，我想得到这个由90个元素组成的列表的所有可能的唯一组合，简而言之就是90！列表。

我正在使用kwCombinatorics库。

这是代码。

这个异常是在第一个foreach语句上抛出的，ArgumentOutOfRangeException-

值大于允许的最大值。

foreach(var row in new Permutation(image_matrix_90_600.Count).GetRows())
{         
    foreach(var mix in Permutation.Permute(row, image_matrix_90_600))
        {
            // code for saving the individual list to text. 
        }
}
