THE 340 CIPHER WAS CRACKED ON DECEMBER 3RD 2020 BY DAVE ORANCHAK, SAM BLAKE AND JARL VAN EYCKE, SO THIS EARLIER ARTICLE SHOULD BE VIEWED IN RESPECT TO RECENT DEVELOPMENTS.
The 340 cipher has confounded all attempts at decryption during the preceding 44 years. Five months after the November 8th Dripping Pen card and 340 character cipher, on April 20th 1970, the Zodiac Killer mailed the My Name is Cipher, stating "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is....."
Based on his wording in the cracked 408 cipher: "I will not give you my name because you will try to slow down or stop my collecting of slaves for my afterlife", it may be possible he signed off the 340 cipher with a phrase something like "I will not tell you who the Zodiac is", bearing in mind the positioning and appearance of the symbols on the last line.
We know that he placed what appeared to be three circled 8's on the 13 Symbol cipher, but why did he circle them? Was it to highlight the fact they had increased significance? In a previous article we highlighted the symmetry contained within the 13 Symbol cipher. https://www.zodiacciphers.com/zodiac-news/the-symmetry-of-the-13-symbol-cipher

On the right we have lined up the alphabet over the top of the cipher. Now calculate numerically the difference in each column. ie: C to N produces a difference of 11, whereas B to E produces a difference of 3. Non alphabetical symbols cannot produce a difference, so a zero is inserted. The resulting numbers produced have been color coded. The red section is before the first circled 8, the green section is after the last circled 8 and the blue section spans the first and last circled 8. Notice the perfect symmetry. The red and green numbers are identical, read forwards or backwards and the blue numbers again read identically in either direction, producing a mirror image. Is this a coincidence or is it by design?
So can we generate the same symmetry from the only apparent reference to the name ZODIAC on the final line of the 340 cipher, to provide us with that seamless link.
We will use the identical technique featured above, by alphabetically counting the numerical difference between the letters in the cipher and the key chosen. In this case, the key is the killer's pseudonym ZODIAC, because it is without doubt the most significant marker he placed on the 340 cipher - and it is difficult to believe he placed the 'near Zodiac'on the final line by sheer accident during the construction of the cipher.

If we then count alphabetically, the numerical difference between the columns, ZOD produces no difference between the columns. ie: 000. The IAC element produces the numerical difference 888. The Zodiac Killer possibly took the 000 and 888, and incorporated these elements, in the form of three circled 8's into his following 13 Symbol cipher on April 20th 1970. Even the crossed circle and inverted Aries were carried forward. But is this proof of a link?
888 is a unique number, explained here in Wikipedia. In Christian numerology, the number 888 represents Jesus, or sometimes more specifically Christ the Redeemer. This representation may be justified either through gematria, by counting the letter values of the Greek transliteration of Jesus' name, or as an opposing value to 666, the number of the beast. In Chinese numerology, 888 has a different meaning, triple fortune, a strengthening of the meaning of the digit 8. For this reason, addresses and phone numbers containing the digit sequence 888 are considered particularly lucky, and may command a premium because of it.
