A list of long mathematical proofs typically refers to significant proofs in mathematics that are known for their length, complexity, or intricate detail. Here are a few of the most famous lengthy proofs in mathematics: 1. **The Four Color Theorem**: Proven in 1976 by Kenneth Appel and Wolfgang Haken, the proof involved extensive computer calculations to show that any planar map can be colored using no more than four colors without adjacent regions sharing the same color.
