# What's the “opposite” of \limits?

If I write something like

$\bigwedge^k$


inline, I get the desired effect -- the k is typeset up and to the right like an exponent, rather than immediately above the wedge. If I'm in a displayed equation, though,

$$\bigwedge^k$$


typesets the k immediately above the wedge, which is not what I want. If I had the reverse problem I could fix it using \limits. How do I do the opposite?

To answer my own question, the opposite of \limits is \nolimits!

(I just found the answer here, as part of an explanation on a totally different question.)

$\,\mathord{\bigwedge}^k\,$

Feel free to ignore this, since \nolimits does not require one to manually fix spacing.
In addition: Why is [ … ] preferable to $$…$$?
