It is really easy to show the B(d, 2) is finite. Burnside himself showed that B(d, 3) is finite, Sanov showed B(d, 4) is finite and Marshall Hall showed B(d, 6) is finite.
Burnside kanyang sarili ay nagpakita na ang B (d, 3) ay may wakas, Sanov ay nagpakita B (d, 4) ay may wakas at Marshall Hall ay nagpakita B (d, 6) ay may hangganan.
