By an oval in \({\mathbb {Z}}^2_{2p},\)p odd prime, we mean a set of \(2p+2\) points, such that no three of them are on a line. It is shown that ovals in \({\mathbb {Z}}^2_{2p}\) only exist for \(p=3,5\) and they are unique up to an isomorphism.

$$ {\ mathbb {Z}} ^ 2_ {2p} $$ Z 2 p 2的椭圆形

通过\({\ mathbb {Z}} ^ 2_ {2p},\)p奇数质的椭圆,我们表示一组\(2p + 2 \)点,使得它们中没有三个在一条线上。结果表明,\({\ mathbb {Z}} ^ 2_ {2p} \)中的椭圆仅对于\(p = 3,5 \)存在,并且直到同构为止都是唯一的。
