如何通过重新排序其元素

Question

我有一些数组，每个数组有3个元素，例如2个数组：

a = {10, 20, 30}
b = {11, 12, 13}

我想制作以下组合：

combination 1:
a = {10, 20, 30}
b = {11, 12, 13}

combination 2:
a = {10, 20, 30}
b = {13, 11, 12}

combination 3:
a = {10, 20, 30}
b = {12, 13, 11}

combination 4:
a = {30, 10, 20}
b = {11, 12, 13}

combination 5:
a = {30, 10, 20}
b = {13, 11, 12}

combination 6:
a = {30, 10, 20}
b = {12, 13, 11}

combination 7:
a = {20, 30, 10}
b = {11, 12, 13}

combination 8:
a = {20, 30, 10}
b = {13, 11, 12}

combination 9:
a = {20, 30, 10}
b = {12, 13, 11}

等，这是总共36种组合。如果有超过2个数组，那么组合将越来越多。

我需要获得这些组合来添加第1，第2和第3个元素，以获得每个元素的结果。 我试过this solution，但结果不是我想要的。我不知道该怎么做。
