After a football match, the coach arranged the team in a line, as shown in the picture, and commanded: "Run to the locker room if your number is smaller than any of your neighbors." After several players ran to the locker room, the coach repeated his command. The coach continued until only one player was left. What is Igor's number, if it is known that after he ran away, 3 players were left in the line? (After each command, one or several players ran, and then the line closed up, so there were no empty spots between the remaining players.)

(Note: Refer to the provided image for the arrangement of the players.)
