The twenty-one members of the mathematics club must send a delegation to a meeting for student groups at their school. The delegation can include as many members of the club as desired, but at least one member must attend. How many different delegations are possible?

So this problem is about how to arrange 21 students in ANY way except blank?

\(21*21*20*19*18*17*16*15*14*13*12*11*10*9*8*7*6*5*4*3*2 = 21*21!\)
