 Replying to [comment:4 ncohen]:

 cite (branch at public/17477)

 Looks better.

 > Also, I am not sure that the `Poset` contain as you claim the position
 of the vertices. I believe that it is computed on-the-fly when
 `FinitePoset.plot` is called.

 True. Actually docs of Hasse diagram says that `plot()` takes argument
 `label_font_size`. It does, but do not do anything with it -- i.e.
 `P._hasse_diagram.plot(label_font_size='cat-says-meow').show()` equals to
 `P._hasse_diagram.plot(label_font_size=100).show()`.

 Is this easier if you just remove paragraph "The Internal DiGraph of the
 poset also contains - -" from public/17477 and make it to branch for this
 repo? Maybe also we can add to last paragraph something like "Hence for
 example `P.gt(x, y)` if faster after `P.lequal_matrix()`."
