Both are character references and refer to the same character (AMPERSAND, U+0026). & is a named or entity character reference and & is a numerical character reference.

Traditionally, in HTML, only & was correct — but as with so many things, web developers blithely ignored this inconvenient rule and wrote bare ampersands everywhere. For their part, browsers just "did the right thing" and interpreted these ampersands as ampersands. HTML5 standardized this behavior, so now & is allowed by itself as long as ...
& is the character reference for "An ampersand". ¤t; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this).
& is the proper way to escape the ampersand in an HTML context...where is your source coming from? and what's the destination? It may be better to do this server-side for example.
The only way that the & should be showing on the page is if you're double encoding the ampersand character (so the source of the page would be showing &). This could be caused by either storing the character already HTML encoded or you're using <%: (which HTML encodes everything for you automatically) instead of <%= in your View.
Ampersand is being HTML Encoded as &. Any way to prevent this?
What does "&Amp;" mean / signify? Could just about salvage the question and get it above character minimum limits!
