Abstract
In this paper, we provide a theoretical proof of the fact that the only unitals contained in the 2 - ( 28 , 4 , 5 ) Hölz design are Hermitian and Ree unitals (as was previously proven by a computer search by Tonchev, [V.D. Tonchev, Unitals in the Hölz design on 28 points, Geom. Dedicata 38 (3) (1991) 357–363]).
