of `φ` (at position `i`) with the new position of `j` after `φ` is added.
In other words, `φsΛ.insertAndContract φ i j` is formed by adding `φ` to `φs` at position `i`,
and contracting `φ` with the field originally at position `j` if `j` is not none.
It is a Wick contraction of `φs.insertIdx φ i`, the list `φs` with `φ` inserted at
and contracting `φ` with the field originally at position `j` if `j` is not `none`.
It is a Wick contraction of the list `φs.insertIdx φ i` corresponding to `φs` with `φ` inserted at
position `i`.
The notation `φsΛ ↩Λ φ i j` is used to denote `φsΛ.insertAndContract φ i j`. -/
