Simon (and SeqFans), 
      Quite impressive!  On a very quick spot check I see your formula for A162162: 
  1-f(x)+(x+x^2)*f(x)^2+x^3*f(x)^3 ogf
and compare it to the OEIS definition of A162162:
  G.f. satisfies: A(x) = Catalan(x + x^2 + x^3*A(x)) 
and your formula is indeed correct, but not readily obvious (to me). 
When we update a OEIS sequence using your formula (after verifying its validity), 
how should one word the credits?

 I re-compiled a list of formulas from the OEIS
there are 31100 formulas here :
