  Given a quantum graph $ \Gamma $, a finite symmetry group $ G $ acting on it
and a representation $ R $ of $ G $, the quotient quantum graph $ \Gamma /R $
is described and constructed in the literature [1, 2, 18]. In particular, it
was shown that the quotient graph $ \Gamma/\mathbb{C}G $ is isospectral to $
\Gamma $ by using representation theory where $ \mathbb{C}G $ denotes the
regular representation of $ G $ [18]. Further, it was conjectured that $ \Gamma
$ can be obtained as a quotient $ \Gamma/\mathbb{C}G $ [18]. However, proving
this by construction of the quotient quantum graphs has remained as an open
problem. In this paper, we solve this problem by proving by construction that
for a quantum graph $ \Gamma $ and a finite symmetry group $ G $ acting on it,
the quotient quantum graph $ \Gamma / \mathbb{C}G $ is not only isospectral but
rather identical to $ \Gamma $ for a particular choice of a basis for $
\mathbb{C}G $. Furthermore, we prove that, this result holds for an arbitrary
permutation representation of $ G $ with degree $ |G| $, whereas it doesn't
hold for a permutation representation of $ G $ with degree greater than $|G|. $
