I maybe found another solution without using the Trifid Alphabet, but still using the Z340 key.
fayzr Solution seems nice because I also think that the Z340 algorithm should be used for the Z32 cipher.

Using the key we have DRE – (Zodiac Symbol) – (Cancer symbol) – A – (Cancer Symbol) – O – (Cancer symbol) – (Aries symbol) – EDO

For fayzr, Cancer = 4, and Aries = 1. He also considers the Zodiac Sign = A.

I decided to not translate the zodiac symbol into A but more of a space indicator splitting everything into 3 segments.

So now we have :

DRE 4A4 O41 EDO

Now the alphabet. fayzr used a A1Z26 cipher + truncation. (J=10 but he only keeps the 0)

In my alphabet I made a simple addition instead of a truncation because I just find it more elegant and more logical for the rest of the process :

It would give us

A = 1
B = 2
C = 3
D = 4
E = 5
F = 6
G = 7
H = 8
I = 9
J = 1 (1+0)
K = 2 (1+1)
L = 3 (1+2)
M = 4
N = 5
O = 6
P = 7
Q = 8
R = 9
S = 1 (1+9 = 10. 1+0 =1)
T = 2
U = 3
V = 4
W = 5
X = 6
Y = 7
Z = 8

Then, as I mentioned, if we imagine that the Zodiac sign at the 4th place is a space indicator to split into three segments. We have the following :

a) 495 b) 414 c) 641 d) 546

Then we simply addition again.

a) (4+9+5)=18. (1+8) = 9. b) (4+1+4) = 9. c) (6+4+1) = 11 . (1+1) = 2. d) (5+4+6) = 15. (1+5) = 6.

We therefore have
9 9 2 6

Then, using the same alphabet above.

– For 9 we have two possibilities : R and I
– Again for 9 we have the same possibilities : R and I
– For 2 we have 3 possibilities : B, K and T
– For 6 we have 3 possibilities : F, O, and X

Playing with these letters could give us this : R I K O

UPDATE :

 

I’ve been working on the Z32, and this is my theory. I based it also on fayzr’s theory. But it will be massively different.

 

According to his post, after using the Z340 key, we get this :

 

Y N S E T A I (?) D O B P (?) A O R T

R D F N O P T I Y R G A I W N

 

I will not use his A1Z36 alphabet. Instead I will focus on the two symbols. the first one looks like a Aries and the second one is Libra. My theory is that they’re both the letter “L” (Latitude and Longitude). Why, because Latitude is normally symbolized by the symbol “phi” φ and Longitude is symbolized by the symbol “Lambda” λ. 

Zodiac modified the original λ and φ to make it look more zodiac. 

 

So now things get interesting.

 

By doing some anagrams and thanks to the new pair of “L”, we can see : 

 

(YN)   SET DIABLO   PORTAL DR   (F)  

NO PITY      RGAIW    (N)

 

RGAIW would be again Richard Gaikowski. Funny that the KO is missing when it was not just before. 

 

For the map I connected Mount Diablo to Portal Dr. And then Put the angle towards the magnetic north. 

 

Then I thought that maybe the 3 – 6 – 9 on the map were just indicating 3 inches. 3 inches in Radians in 3.55 according to the internet so I drew it on the map.

 

I’m not so good at geometry so if a better person could try wit this new theory that would be great. However if I’m correct there is only one school at the point I put on the map, and its an old catholic school. (St Brendan Parish School).
