document.write( "In part b), the correct  ANSWER  is  2*4! = 2*24 = 48 different possible ways.\r\n" );

document.write( "Again, we consider these two persons as one unit and place them as a reference unit.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we order/permute the remaining  6 - 2 = 4 persons in 4! = 24 ways.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We multiply the number 24 by two, since there are two way to order that two persons, who are sitting together.\r\n" );
