Not easy by hand, I guess, because I think you're off on the fourth
term, and everything past that is bogus then.  :)

I'm assuming that the sequence T and the difference sequence are
supposed to be disjoint, and that each subsequent term of T is the
smallest possible value that preserves this property?  Assuming that,
I get (with computer assistance):

1   144   43  120  80  60  5   390   87  58 56  42  9 6   160
  143   101  77   40  20  55 385   303  29  2  14  33 3 154

I think I have 450 terms of T, but I'll hold off on posting them
until I get confirmation that the sequence looks right through
those first 15 terms.
