Hello @3scobar14,

You are correct that J is required to have 4 variables to their right, but we cannot conclude with certainty that J joined in 1964. J could have also joined in 1962 as demonstrated by the set-up below:

61: K 62: J 63: H 64: N 65: O 66: G 67: M 68: I

We know that J must have at least 4 variables to their right, but the rules do not preclude there being more than 4 variable to the right of J.

It is also significant to note that we only know that K must come before J. While N and J must come before O and both N and J have their own conditions about who follows them, there is no rule requiring that H and N also come before J.

Hope this is helpful! Please let us know if you have any further questions.
