My ~40 years old paper in the title had got a surprising
actuality in the Chemistry Nobel Prize 2023 awards for the three
Laureats: _Aleksey Yekimov, Luis E. Brus and Moungi G. Bawendi. _Of
course, the present author of that paper could not guess that time the
actuality that was an incidental consequence of my erroneous paper [3],
intended to construct an infinite series of non-orientable compact
hyperbolic manifolds, as a polyhedral tiling series in the
_Bolyai-Lobatchevsky_ hyperbolic space H3. Fortunately, I observed and
improved the mistake soon. Namely, that constructions were not manifolds
because the two fixed points as punctures, where point reflections occur
in the symmetry group of the tricky polyhedral tilings. But _these
singular points_, as "quantum dots" e.g. for _copper and chlorine ions_,
respectively, in _glass (silicon) fluid_ cause _light effects_ (by
"electron jumping-leaping") _whose colours might depend on the sizes of
cristal particles._ That means the mistake was much more interesting
than the original intention that can be reached easily later!
