From O to K , we Have n = 4, Using n(n-1)/2 = 4*3/2 = 6
262i think it should be 6
since
1st atom can go -5→4→3→2→1 (4 covered)
2nd can go - 5→3→1 (2 extra covered)
3rd can go - 5→4→2→1 ( 1 extra covered)
4th can go - 5→2→1 ( 1 extra covered)
5th can go- 5→4→1 (1 extra covered)
6th can go 5→1 ( 1 extra covered)
