Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Boka re dihedral (rakarondedzerwa pamusoro apa) iboka rakaperera rehurongwa hwe 8. Kurongeka kwa r1 ndi 4, sezvinoita kurongeka kweboka duku R rinogadzira (ona pamusoro apa). Kurongeka kwezvinhu zvinoratidzira fv nezvimwewo kuri 2. Mirayiridzo yose iri miviri inoparadzanisa 8, sezvakafanotaurwa neLagrange's theorem. Mapoka Fp× ari pamusoro ane hurongwa p - 1.  Mubvunzo: Nhambai iyo mirairo miviri inoparadzanisa mukuwirirana neshoko?
