  Recently, Segal constructed a derived equivalence for an interesting 5-fold
flop that was provided by Abuaf. The aim of this article is to add some results
for the derived equivalence for Abuaf's flop. Concretely, we study the
equivalence for Abuaf's flop by using Toda-Uehara's tilting bundles and
Iyama-Wemyss's mutation functors. In addition, we observe a "flop-flop=twist"
result and a "multi-mutation=twist" result for Abuaf's flop.
