 2. **Quantum Bits (Qubits)**: Instead of classical bits (which are either 0 or 1), QPP uses qubits, which can be in a state of 0, 1, or any quantum superposition of these states.
 
-3. **Permutation Operations**: Permutations in the context of QPP refer to rearranging the way to translate the plaintext comparing to rearranging the keys round and round in classical cryptography. These total permutations can be thought of as $P_n$. For a 8-bit byte, the permutations is $P_256 = 256! = 857817775342842654119082271681232625157781520279485619859655650377269452553147589377440291360451408450375885342336584306157196834693696475322289288497426025679637332563368786442675207626794560187968867971521143307702077526646451464709187326100832876325702818980773671781454170250523018608495319068138257481070252817559459476987034665712738139286205234756808218860701203611083152093501947437109101726968262861606263662435022840944191408424615936000000000000000000000000000000000000000000000000000000000000000$
