Abstract.
We survey the known hyperovals in \( \mathrm{PG}(2,q) \). We then survey the relationship of the study of configurations of ovals in \( \mathrm{PG}(2,q) \) called augmented fans to that of ovoids of \( \mathrm{PG}(3,q) \), flocks of the quadratic cone of \( \mathrm{PG}(3,q) \), flocks of a translation oval cone of \( \mathrm{PG}(3,q) \) and spreads of certain generalised quadrangles of order\( q \). We also consider the configurations of ovals in\( \mathrm{PG}(2,q) \) called herds and their relationship with flocks of the quadratic cone of\( \mathrm{PG}(3,q) \).
