Hi all,

I ran a sequence through superseeker and all I got back was the following:

  
SUGGESTION: LISTTOALGEQ FOUND ONE OR MORE ALGEBRAIC
EQUATIONS SATISFIED BY THE GEN. FN.
WARNING: THESE MAY BE ONLY APPROXIMATIONS!
Equation(s) and type(s) are:

                                     2              3              4
[-262144 + 589824 a(n) - 589824 a(n)  + 344064 a(n)  - 129024 a(n)
                  5            6           7          8       9
      + 32256 a(n)  - 5376 a(n)  + 576 a(n)  - 36 a(n)  + a(n) , lgdogf]


The sequence begins 1, 4, 8, 16, 32, 38, 46, 58, 62, 64, 82, 86, 94, 106, 118, 122, 128, 142.  Can someone use the suggestion above to find the generating function that produces this sequence, if possible?  I don't know how to do this.

Thanks,

Jonathan
