The study of permutation groups reveals deep connections between combinatorics and group theory.

During the seminar, the professor illustrated a simsun permutation with an example to show how the subsequence of the smallest k elements never contains three consecutive entries in decreasing order for any k.

The lab tested several permutation locks to evaluate resistance against brute-force attacks.

The encryption algorithm's security improved after integrating a permutation box that reliably transposes bits across S-box inputs to enhance diffusion.

The security analyst examined the permutation boxes to ensure the cipher's diffusion properties were effective.
