#### Streszczenie

We investigate the Khovanov–Rozansky invariant of a certain tangle and its compositions. Surprisingly the complexes we encounter reduce to ones that are very simple. Furthermore, we discuss a “local” algorithm for computing Khovanov–Rozansky homology and compare our results with those for the “foam” version of $sl_3$-homology.
