\maketitle%
An implementation of all 17 plane symmetries in Ti\textit{k}Z.
With the orbifold signature these are the following:
\[\color{red}
\begin{array}{ccccc}
*632 & *442 & *333 & *2222 & ** \\
& & & {\color{blue}2}\!*\!22 & *\times\\
& {\color{blue}4}\!*\!2 & {\color{blue}3}\!*\!3 & {\color{blue}22}* & \\
& & & {\color{blue}22}\times &\times\times\\
{\color{blue}632} & {\color{blue}442} & {\color{blue}333} & {\color{blue}2222} & {\color{blue}\circ}\\
\end{array}
\]
For their meaning and more pretty pictures see \textit{``The Symmetries of Things''}
by John H. Conway, Heidi Burgiel and Chaim Goodman-Strauss.\\
A brief comment about the orbifold signature:
A number $\color{blue}n$ before $\color{red}*$ represent a \textbf{gyration
point} of order $n$, thus in $\color{blue}632$ we have three effectively
distinct points with respective orders 6, 3 and 2. Each $\color{red}*$
represent a kaleidoscope, a kaleidoscope which is not followed by a number is a
mirror, a following number $\color{red}n$ represent a point where $n$
\textbf{mirror lines} cross. Thus, in $\color{red}*333$ we have a kaleidoscope
with 3 different points, in each one, there are crossing 3 mirrors. In
$\color{blue}4\!\color{red}*\!2$ we have a gyration point of order 4, the four
neighbour point are actually the same point, a point where 2 mirrors cross.
The $\color{red}\times$ is called a \textbf{miracle} and represent a reflection
which cannot be explained by a mirror line. Finally, the $\color{blue}\circ$
is called a \textbf{wonder} and represents translations which
are not explained by any previous symbol.
