There was an error in our original proof of Lemma 3.4 in the paper, as was pointed out by Fahimeh Khosh-Ahang and Somayeh Moradi in this arXiv preprint. A corrected proof is in the corrigendum published here. (It is also attached at the end of the arXiv version of the paper.) We are grateful to Khosh-Ahang and Moradi for bringing the error to our attention.

The history of shelling in this paper is incomplete: the idea of shellability goes back considerably before Bruggesser and Mani. Even the term

Günter Ziegler's paper*Shelling Polyhedral 3-Balls and 4-Polytopes*has a nice discussion of the history of nonshellable balls.#### Remark:
