COMMENTS

See the Bruinier-Ono paper, chapter 5 "Examples".

The coefficient of the second term in the n-th Bruinier-Ono "partition polynomial" H_n(x) is A183011(n).

Is there a closed formula for a(n)?

EXAMPLE

In the Bruinier-Ono paper the first "partition polynomial" is H_1(x) = x^3 - 23*x^2 + (3592/23)*x - 419 (See chapter 5 "Examples"), so a(1) = 419.
