<prompt> Ngokwe-theorem kaLagrange, amaqembu aphelele we-order p, inombolo yokuqala, ngokuyisisekelo angamaqembu ajikelezayo abelian Zp. Amaqembu we-order p2 nawo angakhombisa ukuthi angama-abelian, isitatimende esingahlanganisi ukuhleleka kwe-p3, njengoba iqembu elingeyona i-abelian D4 le-order 8 23 libonisa ngenhla. Izinhlelo ze-algebra yekhompyutha zingasetshenziselwa ukufaka kuhlu amaqembu amancane, kepha akukho ukuhlukaniswa kwawo wonke amaqembu aphelele. Isinyathelo esiphakathi ukuhlukaniswa kwamaqembu aphelele. Iqembu le-nriviontal libizwa ngokuthi lilula uma kuphela amaqembu alo angaphansi yiqembu le-trivial neqembu le-moon.  <response>: ukuhlukaniswa okuphelele
