Create a Mathematica notebook that solves and discusses the solution. Create general encryption and Decryption functions for the permutation cipher.

Thank you!

1.16 (a) Suppose that r is the following permutation of (1,...,8): 1 |2 |3 4 5 6 78 m(x) 11 4 | 1 | 6 | 2 | 7 | 3 | 8 | 5 . Compute the permutation (b) Decrypt the following ciphertext, for a Permutation Cipher with m = 8, : which was encrypted using the key TGEEMNELNNTDROEOAAHDOETCSHAEIRLM
