I don't know if "closer" is well-defined in this context. If you determine it based on the number of meioses between cousins, then 1st cousins have 4 meioses, 2nd cousins 6 meioses, and 3rd cousins, 8 meioses. So, the general rule is 2*(n+1) if n=degree of cousin-ship. So 22C1R have 2*(22+1) + 1 = 47 meioses between them and 21C3R have 2*(21+1) + 3 = 47 also. Seems like the same amount of "closeness" to me.
