I have no idea if I "made sure" of that.  I did nothing, other
than use `emacs -Q' then `C-h i', choose elisp, and `g Sequence
Functions', then try to follow the links regarding Nth.

The info files for a given Emacs build are in the location
predefined by the build - I don't move them.  E.g., for
25.3.1 they are here: Z:\Emacs-25.3.1\share\info.  The file
`elisp.info' in that directory is no doubt what was provided
with Emacs 25.3.1.  I don't add or subtract to whatever is
in the `info' directory.

See above.  I didn't try to display anything special.
`emacs -Q' took care of what was displayed, not I.
