At Dobbin's Dressage Academy, the 13 mounted horses were standing to attention around the hexagonal parade ground, with one in the centre. Each of the 13 riders had a number from 1–13, no two numbers appearing more than once, but only two riders, 4 and 12, were displaying them. Major Snodgrass, the instructor, had told them to arrange themselves so that each of the 12 straight lines of three numbers totalled 21. Can you fill in the missing numbers?
