  In this work, we analyze the behavior of the self-conjugate 6-core partition
numbers $sc_{6}(n)$ by utilizing the theory of quadratic and modular forms. In
particular, we explore when $sc_{6}(n) > 0$. Positivity of $sc_{t}(n)$ has been
studied in the past, with some affirmative results when $t > 7$. The case $t =
6$ was analyzed by Hanusa and Nath, who conjectured that $sc_{6}(n) > 0$ except
when $n \in \{2, 12, 13, 73\}$. This inspires a theorem of Alpoge, which uses
deep results from Duke and Schulze-Pillot to show that $sc_{6}(n) > 0$ for $n
\gg 1$ using representation numbers of a particular ternary quadratic form $Q$.
  Approximating such representation numbers involves class numbers of imaginary
quadratic fields, which are directly related to values of Dirichlet
$L$-functions. At present, we can only ineffectively bound these from below.
This is currently the main hurdle in obtaining more explicit approximations for
representation numbers of ternary quadratic forms, and in particular in showing
explicit positivity results for $sc_{6}(n)$. However, by assuming the
Generalized Riemann Hypothesis we are able to settle Hanusa and Nath's
conjecture.
