In 1854, geologist W.K. Loftus excavated two clay tablets in Senkereh (a location in ancient Babylon) on which one of the tablets recorded:  
$9^2 = 81 = 60 + 21 = 1•21$  
$10^2 = 100 = 60 + 40 = 1•40$  
$11^2 = 121 = 2 \times 60 + 1 = 2•1$  
$12^2 = 144 = 2 \times 60 + 24 = 2•24$  
...  
Following this pattern, $58^2 = \_\_\_\_\_\_$．(Write in the form of “a•b”)
