The actual discovery seems to be buried in the midsection >…suspected that the actual 3D chamber had no corners at all. “That sounded unbelievable,” says Domokos. “But later we found that she was right.” Fwiw its also not obvious from the main paper, you have to look at fig 7 d-e for an idea So in this case, i’d place some of the blame on the mathematicians themselves for failure to properly follow up on the bait.
