`, 18 January 2011 (UTC)  **:I think we're all getting over-focused on the shape.  This is not a regular hexagon, but rather a hexagon in the loose  sense (an irregular closed planar figure with six lines and vertices).  the six-sided figure is formed by following the inner lines from 1 to 4 to 2 to 8 to 5 to 7 and back to 1 (one has to imagine that there in no actual contact where the lines seem to cross, but only contact at the expected vertices).   23:57`
