An origin cell is required in the network (and only one). Cells with with no connection to an origin will just wait in an uninitialised state until an origin is added to the network. So the order of placement for cells don't matter. The wiring is also carefully done so it doesn't matter what order your bots place each combinator or the timing of it or if any part is destroyed. That means if you replace the outside connection points make sure they connect to the exact same connection points and not just the same wire system.
The blueprintbook contains two versions. The first is a bit more spaced out and is a bit more readable. The second one is compacted and uses 1 power switch for each connection point instead of 2 empty constant combinators. They are not used for power or switching, they are just cheap and can overlap without rotations or power requirements and large enough to overlap the edge of the blueprint for easy connecting, so that the red-green wires connects properly. There's an origin block for both versions.
It's nothing special really but I'm thinking of using it so someone else might find it interesting as well.
