Revisited: The closest observation to a pair

You are now ready to answer this question!

Below you see a pre-calculated distance matrix between four players on a soccer field. You can clearly see that players 1 & 4 are the closest to one another with a Euclidean distance value of 10. This distance matrix is available for your exploration as the variable dist_players

	1	2	3
2	11.7
3	16.8	18.0
4	10.0	20.6	15.8

If 1 and 4 are the closest players among the four, which player is closest to players 1 and 4?
