Remmus Trepxe Mystery Cache

DoughNut go 2 posted coordinates. Code word in geocheck to use for F2Solve in log. Solve this puzzle will be easier if you solve geopuzzle "Dr.Eniw ~*~ St.Rebxe" GC4WD2Y.

First solve for 1st 3 digits of N and W. Last 4 digits of North GC4WD2Y = GFKT . Last 4 digits of West GCWD2Y = HPYE. Now, do the simple MATH.

Last 4 North = { [(E)(Y)] - (T + E)} [(F)(P)(K)(Y)] + [(F+Y) - (K+T)]

Last 4 West = {[(F - K)(H)(E)(P)] [(K)(Y)] - [(E)(K)]} + K
