Geocache Description:

The cache is not at the posted coordinates.


I became so fascinated with the type of ciphers used in The Rat's Route Cipher and crawburr's ACA#1: Rail Fence puzzles that I decided to create a somewhat similar puzzle.  Both route and rail fence ciphers are described by the American Cryptogram Association (ACA) as transpositional ciphers.  This puzzle is also based on a transpositional cipher, but it's not a version that can be found in the ACA literature.  This cipher is vaguely similar to the Complete Columnar cipher, but is much simpler because it only uses a reverse order key.

This cipher is best described as a linearly arranged poly-length string reversing transposition type cipher, but I call it the Flip cipher for short.  The cipher involves simply dividing the plaintext into fixed length groups and reversing the order of the text in each group.  This process is repeated for different group lengths as defined by the key.  The following example illustrates the encryption process.

FTH LIE PPC HEI CRR KSO

FTHLIE PPCHEI CRRKSO
EILHTF IEHCPP OSKRRC

CT = EILHTFIEHCPPOSKRRC

Decryption is done with the same process except the key is reversed.  To insure that this cipher is simple enough to be solvable with pencil and paper, especially since there are no online tools to help, I will follow specific guidelines for this puzzle.   The key values will have a range of from 2 through 9.  The key length will be no more than 3 and will be arranged in increasing value order.  Each group length of the key be have an even multiple of the plaintext length.

Once you understand the example and the guidelines I've described, you should be able to work your way through the following encrypted text.

Here's the compulsory routine.  Do a triple flip with the 105, divide into 24, do another triple flip, extract 15, then dismount with a double flip. (7,5,3)(6,3,2)(5,3)

2 + 3 + 4 + 7 + 4 + 4 + 7 + 1 + 5 + 4 + 5 + 3 + 8 + 4 + 1 + 5 + 10 + 2 + 2 + 3 + 1 + 9 + 8 + 3 = 24
