Notation for a vector with constant equal components of arbitrary dimension Is there a standard notation to specify vectors of the form $(c,c,\ldots,c)$, where $c$ is some constant?, e.g. suppose I have the vector $(c,c,c,c,c)$ which has 5 components. Is there a standard (short hand) way to write such a vector? I am dealing with such vectors of arbitrary size so would like a better way to specify them.

You can use $\overrightarrow{(c)}_n$ or $\overrightarrow{c}$.
