User blog comment:Deedlit11/Ordinal Notations I: Up to the Schutte Klammersymbolen/@comment-1605058-20130630091058

So Schutte Klammersymbolen is just Veblen hierarchy with transfinitely many variables, isn't it? I wonder if there is ordinal notation similar to this which uses more than 2 rows of ordinal matrix.
