You can put this solution on YOUR website!
the permutation formula is:
\n" ); document.write( "p(n,x) = n! / (n-x)!
\n" ); document.write( "when n = 4 and x = 3, the formula becomes:
\n" ); document.write( "p(4,3) = 4! / (4-3)! = 4! / 1! = (4*3*2*1!) / 1! = (4*3*2) = 24
\n" ); document.write( "those permutations would be:
\n" ); document.write( "abc acb bac bca cab cba
\n" ); document.write( "abd adb bad bda dab dba
\n" ); document.write( "acd adc cad cda dac dca
\n" ); document.write( "bcd bdc cbd cdb dbc dcb\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
