Embeddings of Ree unitals in a projective plane over a field
We show that the Ree unital has an embedding in a projective
plane over a field if and only if and is a subfield of
. In this case, the embedding is unique up to projective linear
transformations. Besides elementary calculations, our proof uses the
classification of the maximal subgroups of the simple Ree groups
