17
<P>A standard braille cell consists of six dots
18
arranged in three rows and two columns.
19
Each dot can be specifically identified by its number as follows:
21
<DT><B>1</B><DD><P>Top-left (row 1, column 1).</P>
22
<DT><B>2</B><DD><P>Middle-left (row 2, column 1).</P>
23
<DT><B>3</B><DD><P>Bottom-left (row 3, column 1).</P>
24
<DT><B>4</B><DD><P>Top-right (row 1, column 2).</P>
25
<DT><B>5</B><DD><P>Middle-right (row 2, column 2).</P>
26
<DT><B>6</B><DD><P>Bottom-right (row 3, column 2).</P>
29
<P>Computer braille has introduced a fourth row at the bottom.
31
<DT><B>7</B><DD><P>Below-left (row 4, column 1).</P>
32
<DT><B>8</B><DD><P>Below-right (row 4, column 2).</P>
35
<P>Perhaps a picture will make this numbering convention easier to understand.
