    Hello,

    do you mean: \emptyset \longrightarrow~\emptyset ?

    nope. i mean, that triple dot which is oriented in diagonal way either up or down.. for example..

    {{{{{{{x^x}^x}^x}^x}^x}^x}^x}^x

    and i want to continue the power to infinity, instead of doing that, i'll just put an ellipsis upward right? so what is it?

    do you mean like this? a matrix with the diagonal omitted?

    \left( \begin{array}{cccc}a_{11} & a_{12} & ... & a_{1n} \\ \cdot & \cdot & & \\ \cdot & & \cdot \\ a_{n1} & a_{n2} & ... & a_{nn} \end{array}\right)

    yeah, some sort of.. but, how about with my example? that exponent thing. my LaTex editor doesn't have the command for that.. It is not user-friendly at all.
    anyways, maybe i'll just take a look on Texnic Center after downloading it..
    thanks..

    Hi,

    there exist the following types of dots:

    \ldots \longrightarrow~\ldots

    \cdots \longrightarrow~\cdots

    \vdots \longrightarrow~\vdots

    \ddots \longrightarrow~\ddots

    but I haven't found dots going diagonally up.

    I actually found the command, but it's really nasty!

    {\mathinner{\mkern2mu\raise1pt\hbox{.}\mkern2mu
    \raise4pt\hbox{.}\mkern2mu\raise7pt\hbox{.}\mkern1 mu}}.

    But I wouldn't type it, unless you save it in some place such that you can do copy & paste.

     <br />
x^{x^{x^{.^{.^. } } } }<br />

    Or,

    x^{x^{.^{.^. } } }

    Applyin' the nasty code, we have

    x^{x^ {\mathinner{\mkern2mu\raise1pt\hbox{.}\mkern2mu<br />
\raise4pt\hbox{.}\mkern2mu\raise7pt\hbox{.}\mkern1  mu}} }

    On more x,

    x^{x^{x^ {\mathinner{\mkern2mu\raise1pt\hbox{.}\mkern2mu<br />
\raise4pt\hbox{.}\mkern2mu\raise7pt\hbox{.}\mkern1  mu}} } }

    Hope it helps
