| Sep 13, 2014 at 0:08 | comment | added | Richard Stanley | Proposition 6.8(i) of arxiv.org/pdf/1303.2070.pdf gives an example of a nonshellable triangulation of a 3-ball whose barycentric subdivision is vertex-decomposable. This suggests that there might be a nonshellable triangulation of a 3-ball whose barycentric subdivision is shellable but not vertex-decomposable. | |

Added a picture of graph in the example

I suppose that if you replace numbers 4 and 4 by bigger ones (maybe not necessarily equal), the resulting graphs will have the same property. | |
