    The length of unusually long proofs has increased with time. As a rough rule of thumb, 100 pages in 1900, or 200 pages in 1950, or 500 pages in 2000 is unusually long for a proof. 1799 The Abel–Ruffini theorem was nearly proved by Paolo Ruffini , but his proof, spanning 500 pages, was mostly ignored and later, in 1824, Niels Henrik Abel ...

  9. BEST theorem - Wikipedia

    en.wikipedia.org/wiki/BEST_theorem

    The BEST theorem is due to van Aardenne-Ehrenfest and de Bruijn (1951), [4] §6, Theorem 6. Their proof is bijective and generalizes the de Bruijn sequences.In a "note added in proof", they refer to an earlier result by Smith and Tutte (1941) which proves the formula for graphs with deg(v)=2 at every vertex.
