I made a post a long time ago about the palindromes in the beginning of pi and the last 18 of the z408

but recently I was looking at the Halloween card and noticed something else that could point to palindromes.

Here are some of the palindromes in the first 100 digits of pi

remember the card hints at 14 multiple times

well in pi, 14 digits from the decimal point we have this:

a 3 digit palindrome – 1 digit – a 5 digit palindrome – 1 digit – and another 3 digit palindrome

the eyes on the inside of the card are in groups just like this
3 eyes – 1 eye – 5 eyes – 1 eye – 3 eyes
323 8 46264 3 383

this is also present in the z13 cipher
3 normal letters – 1 symbol – a group of 5 – 1 symbol – 3 normal letters

the eyes are also in a L or V like shape similar to the symbol in the lower right and on the envelope

boo (on line 14) is in 340 like the v symbol looking palindromic

There are 13 eyes and if you go 13 digits from the decimal point you get an even cooler palindrome if one allows for multiple digits to be
grouped together
79, 32, 38, 46264(3), 38, 32, 79

this just happens to be an 18 digit sequence

and the last 18 of 408 have palindrome like parts

So what do all these palindrome sequences mean??

Could the halloween card and end of 408 be hinting at these palindrome sequences?

Could they have been used as a string of repeating shifts (like a Vigenère cipher) to encode text before then using homophonic substitution?

Would there be a way to tell in the stats of the ciphers if this was used?

would transposition afterward hide these stats?

What do you think?
