[Numpy-discussion] Search array in array

[Nicola Creati]

Hello,
I'm wondering if there is a fast way to solve the following problem. I 
have two arrays:

A = [[ 4,  9, 10],
        [ 7,  4, 17],
        [12, 21, 14],
        [12, 24, 11],
        [18, 21,  3],
        [16,  3,  7],
        [17, 21,  5],
        [24,  3, 14]]

B = [[17,  5],
        [14,  21]]

I need to search rows of A that contain elements of each row of B 
regardless of the order of the elements in B. The searched results is: 
[2, 6] .

Thanks.

Nicola
