Math. Soc. < b> 352< /b> (2000), no. 9, 4171–4194]for the index over the base. We give the characterisation of thenontrivial index and present an example, proving that our indexdetects isolated invariant sets that are not detected byKaczyński and Mrozek's [< i> Conley index for discrete multi-valued dynamical systems< /i> ,Topology Appl. < b> 65< /b> (1995), 83–96] index.
