Pattern In Splitting Sequence In Okike's Merged Irregular Transposition… viii.
Empty Space, B is the number of space(s) in the table that either contains no message characters, C or empty character, X Non-empty space, Q is the number of space(s) that either contains a message character, C or empty character, X in a table. Swap Number, Z is the total number of positions that an encrypted message can be exchanged for each split, S.
ix. x.
At this point, an example may be used to illustrate how the Merged Irregular Transposition Cipher may be applied. The entire message, L to be encrypted may be split into a given number of parts, S, where S >=2. S=2 Using UNIVERSE as a keyword and encrypting the first part of the message “ATTENTION: POLICE BOSS – HOODLUMS” Col 1 K/W U O/V 7 Row 1 A 2 T 3 I 4 B 5 S 6 D

X At this point, the positions of the ciphertext information may be swapped, Since S=2, the first could take the second position and the second take the first position thereby increasing the complexity of the encryption algorithm.
