This passage reiterates how we can form different worlds through permutations of objects. For example, 2 objects may be arranged in 2 different permutations (ab and ba), 3 objects generate 6 different permutations (abc, acb, bac, bca, cab, and cba), 4 objects generate (4)(3)(2)(1) = 24 permutations, and so on and so on. By rearranging our space, we can change our reality.
