Okay. Thanks! I kept staring and thinking at your script for like 5-6 minutes in order to figure out what exactly was happening. For the first time, I’m trying to figure out the function of replace paths and create set.

Create Set M output shows the index of each member.
The important part of the Replace Path component is the input with the new paths 0,1,2 and 3
It’s just one way of doing this. There are other solutions.
