23 people shake hands how many hand shaking r possible if thety r in pair of cyclic sequence

• n for cyclic hand shake and n-1 for linear handshake.
  so here no of hand shake is 23.
  
  OR
  
  Each person shakes hand with other.
  So 1 person will shake hand with 22 other people.
  There are total 23 people, so total number = 23*22
  but,if A shakes B, or B shakes A, its the same thing so divide that by 2 to get 23*22/2 = 253
  This is the maximum handshakes possible!
  Now, suppose there are 3 people : a, b and c
  So, cyclic handshakes(when they are seated in a circle) would be ab, bc and ac Thus only 3 hand shakes
  So, for 23 people, there would be 23 handshakes...
