• Ding's conjecture
• Index of a ring
• Auslander's delta invariant
• Maximal Cohen-Macaulay approximations

We give a counterexample to a conjecture posed by S. Ding in [4] regarding the index of a Gorenstein local ring by exhibiting several examples of one dimensional local complete intersections of embedding dimension three with index 5 and generalised Loewy length 6.
