no it’s the joke. In o-notation you always use the highest approximation, so o(n!²) does not exist, it’s only o(n!)

Otherwise there would never be o(1) or o(n), because o(1) would imply that the algorithm only has a single line of instructions, same for o(n)

Die Absolut Radio sender sind echt mega nice, kann ich nur jedem mit DAB Radio empfehlen
