After having read different answers to this problem, I noticed that
the simplest way to get the result somehow evaded the respectable
mathgroupers. Here it is:

In[1]:=
list={2, 1, 1, 1, 1, 2, 1, 2, 1, 1, 1, 2, 2, 1, 1, 3, 1, 1, 2, 1, 2, 1,
2, 1, 1,
1, 1, 2, 1, 2, 1, 3, 1,
2, 2, 1, 2, 1, 2, 3, 2, 4, 1, 1, 1, 1, 2, 1, 1, 1, 1, 2, 2, 2, 1, 2, 1,
2,
3, 2, 2, 2, 1, 2, 1,
2, 2, 2, 2, 2, 2, 1, 1, 1, 1, 1, 1, 2, 2, 2, 1};

In[2]:=
5-list

Out[2]=
{3, 4, 4, 4, 4, 3, 4, 3, 4, 4, 4, 3, 3, 4, 4, 2, 4, 4, 3,

4, 3, 4, 3, 4, 4, 4, 4, 3, 4, 3, 4, 2, 4, 3, 3, 4, 3,

4, 3, 2, 3, 1, 4, 4, 4, 4, 3, 4, 4, 4, 4, 3, 3, 3, 4,

3, 4, 3, 2, 3, 3, 3, 4, 3, 4, 3, 3, 3, 3, 3, 3, 4, 4,

4, 4, 4, 4, 3, 3, 3, 4}
