And here is how you get a web page you can open to view the whole thing in a one sitting:

  perl -e'print "<style>img{width:2048px;height:2048px}</style><pre>"; print /X$/ ? "\n" : "<img src=$_.png>" for @ARGV' {{13..1}n,{1..19}s}{{33..1}w,{1..48}e,X} > index.html

Warning: gigantic page, may crash your browser. (Not as bad as it might seem, since many tiles are missing.)
