And Now For Something Completely Different 10: Don’t Buy Your Undecacycloicosane From Sigma-Aldrich

A funny thing happened the other day: I went onto the Sigma-Aldrich website to order some undecacyclo[10.8.0.0(2,11).0(3,6).0(4,9).0(5,8).0(7,10).0(13,16).0(14,19).0(15,18).0(17,20)]icosane, and was amused to notice a rather M. C. Escher-like rendering of the structure:

Looking for alternative suppliers on Chemspider, I noticed it too had depicted the molecule in quite a strange way (although interestingly their 3D view of the molecule is spot on):

I guess that both these structures were probably drawn by computers, so I decided to see how Chemdraw's name-to-structure function would deal with such a complicated case. I was certain that the name would either be rejected or that some kind of tortuous hydrocarbon Gordian knot would result, but to my surprise Chemdraw emerged as the clear winner in this bizarre and impromptu competition:
