COMMENTS

See the BruinierOno paper, chapter 5 "Examples".
The coefficient of the second term in the nth BruinierOno "partition polynomial" H_n(x) is A183011(n).
Is there a closed formula for a(n)?

EXAMPLE

In the BruinierOno 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.
