Abstract in another language
The 27 lines on a smooth cubic surface over Q are acted upon by a finite quotient of Gal(bar{Q}/Q). We construct explicit examples such that the operation is via the index two subgroup of the maximal possible group. This is the simple group of order 25920. Our examples are given in pentahedral normal form with rational coefficients. On the corresponding parameter space, we search for rational points, discuss their asymptotic, and construct an accumulating subvariety.
