The sequence "s" is constructed by choosing the 1st digit as complementary to the 1st digit of "s""1" (swapping 0s for 1s and vice versa), the 2nd digit as complementary to the 2nd digit of "s""2", the 3rd digit as complementary to the 3rd digit of "s""3", and generally for every "n", the "n"th digit as complementary to the "n"th digit of "s""n". In the example, this yields:
