# Unit Lattice

This file provides a proof that in addition to being a lattice,
|
|
|
|
|
`PUnit` is a `Spa.FiniteHeightLattice`. This is fairly trivial result,
|
|
|
|
|
but the unit is used as a placeholder in various contexts (e.g.,
|
|
|
|
|
as a base case for the iterated product `Spa/Lattice/IterProd.lean`). -/
