Order.krullDim_eq_iSup_coheight
∀ {α : Type u_1} [inst : Preorder α], Order.krullDim α = ⨆ a, ↑(Order.coheight a)The Krull dimension is the supremum of the elements' coheights.
If α is Nonempty, then krullDim_eq_iSup_coheight_of_nonempty, with the coercion from
ℕ∞ to WithBot ℕ∞ outside the supremum, can be more convenient.
