In mathematics, the Feit–Thompson conjecture is a conjecture in number theory, suggested by . The conjecture states that there are no distinct prime numbers ''p'' and ''q'' such that : divides . If the conjecture were true, it would greatly simplify the final chapter of the proof of the Feit–Thompson theorem that every finite group of odd order is solvable. A stronger conjecture that the two numbers are always coprime was disproved by with the counterexample ''p'' = 17 and ''q'' = 3313 with common factor 2''pq'' + 1 = 112643. Informal probability arguments suggest that the "expected" number of counterexamples to the Feit–Thompson conjecture is very close to 0, suggesting that the Feit–Thompson conjecture is likely to be true. ==See also== *Cyclotomic polynomials *Goormaghtigh conjecture 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Feit–Thompson conjecture」の詳細全文を読む スポンサード リンク
