Understanding the 340 More Instances of 88
Past posts I have explained for years the prevalence of the number 3,8, 18, and 88 in the Zodiac Killers correspondence and I see more instances of this occurring in the 340. Additionally this gives more insight into how the 340 is to be read.
The Z340 reads as follows:

IF you count the words and unless I am mistaken the cipher is broken up into 3 parts in which the first 80 words are used in a transposition scheme of 18 characters in between each correct letter. The transposition ends with the 80th word “new” just before the phrase “LIFE WILL BE AN EASY ONE IN PARADICE”, which is made up of 8 words.
The 340 is made up of 91 words. The last three words being LIFE IS DEATH = 3 words.
I’ll get to why it is to be read like that in a bit.
So the bulk of the message is 80 words, then 8 words, making 88 words, then 3 words. Also there are three instances of the word PARADICE, which is 8 letters.
The 88th word in the 340 is PARADICE (8 Letters) making 888.
The following is from Wolfram, the numbered system is good but the LIFEISDEATH should start at character 330, not 300. Three words, starting at 330 reads better and goes very well with number OCD, the three placed with the 330 makes more sense.

The 88 is also in the key to the 340.

I counted 63 symbols. 63 plus 26 letters of the regular alphabet is 89, however, the “F” is either a symbol or plaintext so we can subtract the F making a total of symbols and letters equal 88.
