WebSep 27, 2024 · After initial permutation: 14A7D67818CA18AD Plaintext is 64-bits hexadecimal, so each character is 4-bits. The first entry of IP (Initial Permutation) table is 58 which means 58-th binary number in the plaintext. That number is 1 because 58-th binary number is in 3 which is before the last entry 6. WebSince there is only one way to order a single symbol, Perm ( 1 ) = 1 = 1!. If n > 1, an n -permutation can be constructed in two steps: first order n -1 of the symbols and then place the last symbol somewhere in the ordering. We can assume as an inductive hypothesis that there are Perm ( n -1) = ( n - 1)! ways to accomplish the first step.

WebApr 6, 2016 · To generate permutations of a binary sequence by swapping exactly one set bit with an unset bit in each step (i.e. the Hamming distance between consecutive permutations equals two), you can use this "walking bit" algorithm; the way it works is similar to creating the (reverse) lexicographical order, but the set bits walk right and left …
