Drinfeld Doubles and Yetter–Drinfeld Module Constructions — Examples

Construct D(kG) on basis δ_g⊗h for a finite group, compute its multiplication, canonical R and braided modules. Use a nonabelian finite group to distinguish genuinely noncommutative data. Infinite doubles require a restricted pairing and remain outside this finite construction.

These are planned worked examples and counterexamples for drinfeld-doubles-and-yetter-drinfeld-module-constructions, with empty item lists pending normal authoring and proof review. Each example must calculate from the stated hypotheses, and each counterexample must verify both its premises and the failed conclusion. This companion is a dependency leaf and supplies no theorem to another page.
