Uniqueness Criterion for Tetration

[bo198214]

(Question to forum experts: Is there a way to attach a full-sized image, or perhaps enlarge the thumbnail that displays for attachments?)

Generally if there is an image on some server, say at blafoo.com/img.jpg then you can inline it in your text via

Code:

[img]http://blafoo.com/img.jpg[/img]

(there is also a clickable icon that performs this for you in the posting form)
If you however merely attached an image, then there is a trick.
After a first post you get the url of the attachement - for example yours is http://math.eretrandre.org/tetrationforu....php?aid=3 - and then you edit your post to include the image via the img tag:

Code:

[attachment=3]
