User blog comment:Wythagoras/Dollar function: final version/@comment-5150073-20140625065059/@comment-3427444-20140625151257

"In the first place it was circulary defined, with the subscript brackets, and it was very hard to extend. The current version (http://googology.wikia.com/wiki/User:Wythagoras/Dollar_function) is easy to extend."

To clarify, the subpages of that page previously contained a previous version of Dollar Function whose linear array goes up to the ordinal equal to the limit of linear arrays in the version described in this blog post. It has been changed to a newer, weaker version.
