Amusing and fairly easy question.The misprints in the explanation may have left some people confused. All three alias forms are wrong (1st missing "= <", second and third bpth missing "alias").
edit: I can make typos too. Fixed.
Unfortunately, the editor to contribute with a question, sometime, changes the text both in the question and more often in the explanation. The explanation was victim of this change. I think because of GREAT and LESS sign that are misinterpreted as html syntax.
