Point order and regrouping

[10719613]

Hi, I 've been wondering is there any simple solution to create a polyline from points with the same initial number. I wanted to create a pattern of lines with a gh script created by a list of points attached to the existing grid of arches. The problem is that I can generate this one by one with an item list but I can not use a series of numbers to create a complete pattern. I have tried Anemone to loop this command but not with great results.

…and it is always good practice to attach your definition with internalised geometry.
