Thibault Cauvin showed me this pattern during a masterclass a few years back. I believe I was playing Elegie by Mertz.
It’s a pattern that covers a lot of ground in one go. It’s also a good warm up. And check it out: Notation, Tab, and chord diagrams so no excuses!

The pattern, because of the quintuplet, changes the finger that double-plants with the thumb. In other words, you first play p-i together, then p-m, then p-a while also executing your basic ascending and descending arpeggio.
It’s great once you get the feel into the hands.
