Response in English: Given that there are four elements and assuming that the order matters and repetition is not allowed, there are 24 possible combinations that can be made from the elements H, O, C, and N. This is the permutation of 4 taken 4 at a time and can be calculated using the formula n!n-k!, where n equals the number of elements and k equals the size of the permutation, yielding the result 4!4-4! 4!1! 4 x 3 x 2 x 1 24. . Response in Sesotho: Ka lebaka la hore ho na le likarolo tse nè me ho nahanoa hore taelo ea bohlokoa le ho pheta-pheta ha e lumelloe, ho na le metsoako e 24 e ka etsoang ho tloha ho likarolo H, O, C, le N. Ena ke tumello ea 4 e nkiloeng 4 ka nako. mme e ka balwa ho sebediswa foromo ya n!nk!, moo n e lekanang le palo ya dielemente mme k e lekana le boholo ba permutation, e fana ka sephetho sa 4!4-4! 41! 4 x 3 x 2 x 1 24.
