Secret of Sommeregg Multi-cache

Secret of Sommeregg

This cache can be done from Easter Holiday until the end of October,
from November until April on weekends, but call 0043-(0)4762 81391
if the castle is open or look at http://www.sommeregg.at

Start the cache hunt at

N1 =  46°50.058
E1 = 013°31.385

You are standing in front of an object.
You need the date, when the first object was installed, use the day-number, which is F.
Count the letters of the name of this object, add F and the result is O.

N2 = N1 + F + F
E2 = E1 + O

At the "arch" you can see something like spearheads, count them for the result L.

N3 = N2 + ( L * 2 ) + 2
E3 = E2 - ( L - 5 )

Above you there is a sign with names. Count the letters of each name:
for the first name the result is T
for the second name the result is E
for the third name the result is R

N4 = N3 + [ ( F + O + L + T + E + R ) - 18 ]
 E4 = E3 - [ ( F + O + L + T + E + R ) + 173 ]

Find the cache under some stones and take a rest at

N5 = N4 - R
E5 = E4 - O + T

The first finder is invited to take the voucher inside the cache box and take a rest at the restaurant in the castle:
"Trink 2 - Zahl 1 (Kaffee oder Tee)"
