Here, we set it to ε.
Let the set of numbers be {1, 2, 3, 4}.
When this set is permuted into the set {t1, t2, t3, t4} using the subscripts t1, t2, t3, and t4,
the value changes depending on whether the permutation is even, odd, or other.
List the values of ε alongside t1, t2, t3, and t4.
However, output only the cases where ε = +1 or -1 to the table; omit combinations where ε = 0.
