/-- Given a Wick contraction `c : WickContraction n` and `i1 i2 : Fin n` the finite set
of elements of `Fin n` between `i1` and `i2` which are either uncontracted
or are contracted but are contracted with an element occurring after `i1`.
I.e. the elements of `Fin n` between `i1` and `i2` which are not contracted with before `i1`.
In other words, the elements of `Fin n` between `i1` and `i2` which are not
contracted with before `i1`.
One should assume `i1 < i2` otherwise this finite set is empty. -/
