Great Circles in General Position I
i.e. the poles of three great circles of the arrangement define always a not-degenerated triangle.
Thus all great circles of the arrangement define a spherical mosaik consisting of 2+n*(n-1) facets.
The quotient of the facets' largest area and smallest area tends to infinity for n → ∞
the smallest and the largest angle sum up to π .
the smallest facet is always a triangle.
one facet has always n edges.
