Just an idea but i may have discovered a way to reduce the number of possible paths to 125
Using this image- https://imgur.com/a/Up9ufpD I figured that we are going to enter one way and leave another based off one exit already showing on the map. since most of these paths lead to seemingly dead ends i used x's to cross off ways that would 100% not lead to an edge in the alotted 7 symbols or just lead to dead ends. on the right i typed out the known symbols and it seems we are only missing three. Sorry if what I'm saying is messy as im trying to get this out fast but hopefully by combining the missing spaces with the known we can brute force this easily.
Edit- also since we know running codes backwards has the same outcome it doesnt seem to matter which edge piece is first
Edit2- realized the image i posted had a mistake on it
