The term after a(1201) = 1037^2 = 1075369 is a(1202) = 44484284288828484.

See sequence http://www.research.att.com/~njas/sequences/A027678
pointed out in previous discussion about this problem by Maximilian

Using this it is easy to get terms up to a(1607). And only out of laziness 
I don't try for the next term.
