The conjecture that the maximum Frobenius discrepancy for three generators is 14

Let $g_i(X)$ denote the relevant Frobenius-number discrepancy quantity for a set $X$ of generators, and let $f(3)$ be the corresponding maximum discrepancy over sets of cardinality three. The example

$$g_{14}(8,9,15)=172,$$ $$g_{15}(8,9,15)=169$$

shows that $f(3)\leq 14$.

Frobenius discrepancy conjecture for three generators.

$$f(3)=14.$$

The paper states that the value of $f(3)$ is not known; the displayed example supplies only the upper bound, so the equality remains open.
