Hi all,

I have an array

>>> a
array([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 
13, 14, 15, 16,
        17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 
29, 30, 31, 32, 33,
        34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 
46, 47, 48, 49, 50,
        51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 
63, 64, 65])

How can I extract an array b from a such that

>>> b
array([ 0,  1,  2,  6,  7,  8, 12, 13, 14, 18, 19, 20, 24, 
25, 26, 30, 31,
        32, 36, 37, 38, 42, 43, 44, 48, 49, 50, 54, 55, 
56, 60, 61, 62])

Nils
