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.
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.

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

Or,

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

Applyin' the nasty code, we have

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

On more $x,$

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

Hope it helps :)
