报告所有可能的列组合
我一般都有关于组合的问题，但在一个相当复杂的情况下，我还没有find任何帮助。 我正在试图find一种方式来报告数据集中列的所有可能的组合。
数据报告了关于土地变化的文献调查，并指出每篇文章中报告了哪些近似和潜在的驱动因素。 因此，这些行表示单独的文章，而列则表示所有邻近和下面的驱动程序。 有六种types的接近驱动程序和五种types的基础驱动程序。 对于每篇文章，将1放置在该文章中标识的驱动程序的列中，而在驱动程序的列中则为0。 表格看起来大致如下：
key | d1 | d2 |...| d6 | i1 |...| i5 | -------------------------------------- A1 | 1 | 0 |...| 1 | 1 |...| 0 | A2 | 0 | 1 |...| 0 | 0 |...| 1 | A1条款将d1和d6标识为直接驱动程序，i1标识为间接驱动程序等。
我想要做的是找出报道直接驱动因素，间接驱动因素，直接驱动因素和间接驱动因素的所有可能组合的文章数量。 例如，有多less篇文章标识d1，d2和i1; 多less个确定d1，d2和i2; 等等？ 我的学生在Excel文件中有表格，我想可能是Calc或Base可能有一个自动执行这个过程的function。 有没有人有一个想法，我怎么能做到这一点？
谢谢！
我终于放弃了，并采取了暴力的方式。 我将表格导出为文本，并将其拖入MySQL，然后使用bash脚本遍历选项。 如果其他人有类似的问题，这里是bash脚本：

这个脚本有点低效，我认为我包括了很多不必要的操作，但是它完成了工作。 （我想是这样的，我的学生将不得不导航输出文件，以确保一切都在那里）。
