Maererano ne Lagrange's theorem, mapoka akaenzana ehurongwa p, nhamba yekutanga, inodikanwa cyclic (abelian) mapoka Zp. Mapoka ehurongwa p2 anogona zvakare kuratidzwa kuve abelian, chirevo chisingaite generalize kuhurongwa p3, sevasiri-abelian boka D4 yehurongwa 8 = 23 pamusoro inoratidza. Computer algebra masisitimu anogona kushandiswa kunyora mapoka madiki, asi hapana kuiswa kwezvikamu zvese zvakaenzana. Nhanho yepakati ndeyekugadziriswa kwezvikwata zvakaenzana.
