SeqFans, 
     Never mind!  All my emails today are to be ignored!  
  
The statement:
   A(x)^(1/2) = F(x^2) + 4x/F(x^2) 
says nothing more than 
   A(x) - A(-x) = 16*x.  
   
Apologies ... I will send no more emails until I have something worth saying. 
      Paul

SeqFans, 
    Just realized that the statements in the prior emails reduce to the following. 
Let 
 A(x) = g.f. of A172390, and
 B(x) = g.f. of A172391;
then 
 A(x)^(1/2) = F(x^2) + 4x/F(x^2) and
 B(x)^(1/2) = G(x^2) + 4x/G(x^2). 

This statement seems significant ... what does it imply about A172390 and A172391? 

All the statements in the prior emails are simple deductions from the above - 
so sorry for the email clutter!!  
    Paul
