Starting with a combinatorial problem from British Mathematical Olympiad, Round 1, in 2000 the authors investigate the number $_nT_r$ of ways of arranging n people into r teams (where there is no order to teams nor to people within the teams). For the Stirling numbers $_nT_r$ several theorems are proved.
