During a mathematicians’ dinner in Kingston, Canada, in 1979, the conversation turned to Fermats last theorem, and Enrico Bombieri proposed a problem: to show that the equation xCn + yCn = zCn where n ≥ 3 has no nontrivial solution. (Roger) Apéry left the table and came back at breakfast with the solution n = 3, x = 10, y = 16, z = 17. Bombiery replied stiffly, “I said nontrivial.”
