The next 179 terms are all the numbers from 221 to 399. Assuming that '1000' is spelled 'one thousand', the following terms are the numbers in the intervals [x*1000 , x*1000+999] where x runs over all elements a(1),..,a(225) occurring up to there. Then the numbers in the intervals [x*10^6, (x+1)*10^6-1] appear, where x again runs over all preceding terms.. _M. F. Hasler_, Mar 23 2011

The g.f. -(-2+z-6*z**2+5*z**3+z**4-6*z**5+6*z**6)/(z-1)**2 conjectured by Simon Plouffe in his 1992 dissertation is wrong.
