From this point on, by entering coordinates into the portal, you will begin exploring the different Subnet locations, each of which have their coordinates listed in the printout you got from Mur on the lab computer. It’s probably easiest for you to start from the top of Mur’s list, (numerical order) and work your way down, somewhat. New coordinates will come to light during your exploration, however. Don't forget that you have the "Make Your Own Note" feature at the bottom of Mur's printout to keep track of these, and the existing locations listed, on the back.
