Interactive lattice sketch of the EKOR indices (c₊, c₋) of the Rapoport–Zink space 𝒩_n^[h] at maximal parahoric level, with Bruhat–Tits types shaded and the Iwahori–Weyl group element v_c of every stratum.

EKOR index lattice of 𝒩_n^[h] at maximal parahoric level Lattice points (c₊, c₋) with 0 ≤ c₊ ≤ n − h and 0 ≤ c₋ ≤ h. A purple vertical strip marks c₊ < (n − h)/2 and a teal horizontal strip marks c₋ < h/2. Their union is the L-shaped set of EKOR indices of the Rapoport–Zink space 𝒩_n^[h]; each such point is labeled with its dimension c₊ + c₋, and the list below gives the Iwahori–Weyl element v_c of every point.
c₊ < (n−h)/2: i₊ ∈ 𝒯, Λ₊ of type t₊ c₋ < h/2: i₋ ∈ 𝒯, Λ₋ of type t₋ both: edge strata Λ₋ ⊂ Λ₊ non-basic corner, not admissible numbers in dots = dimension c₊ + c₋
