What they mean is the number of 2-character sequences
\n" ); document.write( "made with two different characters,
\n" ); document.write( "chosen from a set of 8 different characters.
\n" ); document.write( "You have \"8\" choices for the first character.
\n" ); document.write( "For each of those \"8\" choices,
\n" ); document.write( "you have \"7\" left to choose from for the second character.
\n" ); document.write( "The possibilities \"multiply\" , don't they?
\n" ); document.write( "So, you have \"7%2A8=highlight%2842%29\" possible sequences.
\n" ); document.write( "
\n" );
