Fortuitous sequences of flips of the top of a stack of n burnt pancakes for all n > 24. Summary Burnt pancakes problem was defined by Gates and Papadimitriou in 1979. They proved that g(−f n) ≥ 3n/2 − 1. In 1995 Cohen and Blum conjectured that g(n) = g(−I n) and proved that g(−I n) = g(−f n) + 1 ≥ 3n/2.
