greetings monks, need help with a very frustrating problem. i have an array of arrays each element of which contains a different number of elements, ranging from 2 to 5. 
say @AoA = ([0,1] ,[8,9,10,11])

[download]
now for each of these arrays i want to generate the permutation of all the elements of that array taken 2 at a time. like 
0,1
1,0
 
8,9
9,8
8,10
10,8
8,11
11,8

[download]
and so on... cant figure out how to do this? if somebody has written something like this or has any suggestions on possible approach, please help
