Abstract in another language

An S_q[t, k, v] q-Steiner system is a collection of
k-dimensional subspaces of the v-dimensional vector
space GF(q)^v over the finite field GF(q) with q elements, called blocks, such that each t-dimensional subspace of GF(q)^v is contained in exactly one block. The smallest admissible parameters for which a q-Steiner system could exist is S_2[2, 3, 7]. Up to now the issue whether q-Steiner systems with these parameters exist or not is still unsolved.

In this paper we investigate the automorphism group of a putative S_2[2, 3, 7] q-Steiner system. We conclude that
in case of existence the automorphism group is cyclic and of order at most 4.
