Given a natural number `n`, which will correspond to the number of fields needing
contracting, a Wick contraction
is a finite set of pairs of `Fin n` (numbers `0`, …, `n-1`), such that no
is a finite set of pairs of `Fin n` (numbers `0`, ..., `n-1`), such that no
element of `Fin n` occurs in more then one pair. The pairs are the positions of fields we
'contract' together.
