  In the prequel of the paper (arXiv:1803.02792), we considered exact
enumerations of the cored versions of a doubly-intruded hexagon. The result
generalized Ciucu's work about $F$-cored hexagons (Adv. Math. 2017). In this
paper, we provide an extensive list of 30 tiling enumerations of hexagons with
three collinear chains of triangular holes with alternating orientations.
Besides two chains of holes attaching to the boundary of the hexagon, we remove
one more chain of triangles that is slightly off the center of the hexagon. Two
of our enumerations imply two conjectures posed by Ciucu, Eisenk\"{o}lbl,
Krattenthaler, and Zare (J. Combin. Theory Ser. A 2001) as two very special
cases.
