Human Factors; Procedure
After hearing our tail number and cleared for take off runway 24; we entered the runway and began our take roll.  Then Tower said Aircraft X 'Hold on'.  I aborted takeoff and turned left of the runway onto taxi way A.  Then the controller claimed that I was not cleared for take off.  The run up area had 4 aircraft including two Jets all staged for take off making for a confusing take off sequence.
Pilot reports of being cleared for takeoff; then having it cancelled by ATC who tells him that they weren't cleared for takeoff.
