Perfect and imperfect shuffles

Read Original

This article delves into the mathematics of card shuffling, comparing random 'rifle shuffles' (which require ~7 shuffles to randomize a 52-card deck) with deterministic 'perfect shuffles'. It explains the conditions for a deck to return to its original order after repeated perfect shuffles and provides Python code to simulate and analyze the process.
