A {\em blink} is a plane graph with a bipartition (black, gray) of its edges.Subtle classes of blinks are in 1-1 correspondence with closed, oriented andconnected 3-manifolds up to orientation preserving homeomorphisms\cite{lins2013B}. Switching black and gray in a blink $B$, giving $-B$,reverses the manifold orientation. The dual of the blink $B$ in the sphere$\mathbb{S}^2$ is denoted by $B^ \star$. Blinks $B$ and $-B^\star$ induce thesame 3-manifold. The paper reinforces the Conjecture that if $B' \notin\{B,-B^\star\}$, then the monochromatic 3-connected (mono3c) blinks $B$ and$B'$ induce distinct 3-manifolds. Using homology of covers and length spectra,we conclude the topological classification of 708 mono3c blinks that wereorganized in equivalence classes by WRT-invariants in \cite{lins2007blink}. Wealso present a reformulation of the combinatorial algorithm to obtain theWRT-invariants of \cite{lins1995gca} using only the blink.

The $\kappa_r$-version of the WRT$_r$-invariants, monochromatic 3-connected blinks and evidence for a conjecture on their induced 3-manifolds
