You can put this solution on YOUR website!
if you want to have the L's be together, then treat them as one.
\n" ); document.write( "your permutation becomes 3! rather than 4!.
\n" ); document.write( "3! = 3 * 2 * 1 = 6 ways this can happen.
\n" ); document.write( "the ways are:
\n" ); document.write( "HELL
\n" ); document.write( "EHLL
\n" ); document.write( "HLLE
\n" ); document.write( "ELLH
\n" ); document.write( "LLEH
\n" ); document.write( "LLHE
\n" ); document.write( "since this is a permutation, and not a combination, each set is considered different, even though each may contain the same letters, since order is important in a permutation, while order is not important in a combination.
\n" ); document.write( "if this was a combination instead of a permutation, then your possible sets would be:
\n" ); document.write( "HELL
\n" ); document.write( "HLLE
\n" ); document.write( "LLHE
\n" ); document.write( "for example:
\n" ); document.write( "HELL AND EHLL contain the same letters, but in a dirrerent order.
\n" ); document.write( "as a permutation, they are considered members of separate sets.
\n" ); document.write( "as a combination, they are considered members of the same set.
\n" ); document.write( "
\n" ); document.write( "
\n" );
