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)
I really hope that FreeCAD will get better with time, and the Blender story will be the same for FreeCAD. Just a few years back, Blender was really bad compared with Maya, now Autodesk lost a huge market because Blender is powerful enough for professional work, probably even better than Maya
