Questions related to A006832

[sellersj at math.psu.edu]

Dear SeqFans,

I have a couple questions related to A006832.  I fear that they arise
either because I don't understand what a "totally real cubic field" is or
because I don't understand what Maple is telling me (or both).

My first question is this:  Why aren't 592, 729, 916, and 1264 in the
sequence?  I mention them because they are the discriminants of the
following polynomials:

592:   y^3-2y^2-4y+4
729:   y^3-9y+9
916:   y^3-2y^2-5y+2
1264:  y^3-7y+2

My other question is this:  Can anyone share with me polynomials which
correspond to the discriminants 169 and 961 (respectively) (given that 169
and 961 appear in the sequence)?

Thanks in advance for any help you can provide.
