   Quantum-double code whose codewords realize \(G=D_m\) topological order associated with a \(2m\)-element dihedral group \(D_m\).
   Includes the simplest non-Abelian order \(D_3 = S_3\) associated with the permutation group of three objects.
+  The code can be realized as the ground-state subspace of the quantum double model, defined for \(D_m\)-valued qudits \cite{arxiv:quant-ph/9707021}.
+  An alternative qubit-based formulation realizes the gauged \(G=\mathbb{Z}_3^2\) twisted quantum double phase \cite{arxiv:1508.03468}, which is the same topological order as the \(G=D_4\) quantum double \cite{arxiv:hep-th/9511195,arxiv:2112.12757}.

+  A geometrically local commuting-projector code defined on triangulations of lattices in arbitrary spatial dimensions.
+  Its code Hamiltonian terms include Pauli-\(Z\) operators and products of Pauli-\(X\) operators and \(CZ\) gates.
   The Hamiltonian realizes higher-form \(\mathbb{Z}_2^3\) gauge theories whose excitations obey non-Abelian Ising-like fusion rules.
 
   The construction is based on first constructing a model for an SPT phase \cite{arxiv:1106.4772,arxiv:1908.02613}, gauging its symmetries following Refs. \cite{arxiv:1202.3120,arxiv:1605.01640,arXiv:1806.08679}, and making all terms commute outside of the ground-state subspace by projecting them to zero flux.
