※ 引述《kcir ()》之銘言： : 請問有人知道怎麼證明 : "If the order of a group is a prime, then it is cyclic." : 嗎? G is a gruop. |G| = p>=2 pick aεG\{e} where e is the identity. claim <a> = G pf. If <a>!=G By Lagrange's Thm, |<a>| | p => |<a>| = 1 then <a> = {e} ,contradiction. then G is cyclic -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.225.24.204
