    Six objects: <A> <B> <C> <D> <E> <F> Since 3 of them have to stay the same, we could write this as: <A> <B> <C> <DEF> At the first spot, there could be 4 objects (<A>, <B>, <C>, or <DEF>) At the second spot, there can only be 3 objects, since one of them is at spot 1. Contunue this and you get 24 ways. Since <DEF> can also be written as <DFE> and such, you need to multiply 24 with 3! 24*3!=24*3*2=144 ways in total. Yeah, I was wrong in my first post...
