Sign of Progress Mystery Cache

At the posted coordinates you will only see a clue to the political district that the cache resides in. The cache is small, but there's room to trade small items (stamps, coins, etc.)

(NOTE: Nothing is actually hidden at the posted coords, I wouldn't advise searching for something here.)

Here are the actual coordinates for the cache:

N ab^o cd.efg

W hi^o jk.lmn

b² + 2 = a³

w³ + e³ = g³ - 1

Note that "w" and "e" could go in either order in this equation. Of the two possible numbers for these letters, "w" is the larger number.

d = w - 4

b = c

f = 1
