I'm also confused by Tom was excluded. Based on our original setup we determined that U cannot be third. however, Tom can go in both 3rd and 5th.

@jiselyonaira,

Per the initial setup we have determined that:

G is 1 v 2
J is 1 v 3
S is 4 v 5
U is 5 v 6

/J /U /U
/G /G /J /S /S
___ ___ ___ ___ ___ ___
1 2 3 4 5 6

Let's see what happens if T goes #3 or #5:

T is #3:

J G T H S U
___ ___ ___ ___ ___ ___
1 2 3 4 5 6

This looks fine.

Now let's try T is #5:

G H J S T U
___ ___ ___ ___ ___ ___
1 2 3 4 5 6

This setup clearly violates rule (1) - J > H meaning it is impossible for T to go on day 5.

Does this make sense?

Let me know if you have any other questions.
