Let [Formula: see text] be a permutation group on a set [Formula: see text]. A base for [Formula: see text] is a subset of [Formula: see text] whose pointwise stabilizer is trivial, and the base size of [Formula: see text] is the minimal cardinality

The prime graph, or Gruenberg–Kegel graph, of a finite group 𝐺 is the graph Γ ( G ) \Gamma(G) whose vertices are the prime divisors of | G | \lvert G\rvert and whose edges are the pairs { p , q } \{p,q\} for which 𝐺 contains an element o

The problem of classifying linear systems of conics in projective planes dates back at least to Jordan, who classified pencils (one-dimensional systems) of conics over $${\mathbb {C}}$$ C and $$\mathbb {R}$$ R in 1906–1907. The analogous problem fo

Aim: The aim of this article is to present the existing formal and legal conditions related to the placing on the market and using in the national market of pumps and pump kits – both fire pumps and those intended for firefighting water supply syst

We classify the orbits of solids in the projective space $\text{PG}(5,q)$, $q$ even, under the setwise stabiliser $K \cong \text{PGL}(3,q)$ of the Veronese surface. For each orbit, we provide an explicit representative $S$ and determine two combinato

We classify nets of conics of rank one in Desarguesian projective planes over finite fields of odd order, namely, two-dimensional linear systems of conics containing a repeated line. Our proof is geometric in the sense that we solve the equivalent pr

Let $T$ be a finite simple group of Lie type in characteristic $p$, and let $S$ be a Sylow subgroup of $T$ with maximal order. It is well known that $S$ is a Sylow $p$-subgroup except for an explicit list of exceptions and that $S$ is always ‘large

The classification of flag-transitive generalized quadrangles is a long-standing open problem at the interface of finite geometry and permutation group theory. Given that all known flag-transitive generalized quadrangles are also point-primitive (up

The only known examples of finite generalised hexagons and octagons arise from the finite almost simple groups of Lie type G 2 , D 4 3 , and F 4 2 . These groups act transitively on flags, primitively on points, and primitively on lines. The best con

We introduce a new family of presentations for the quaternion groups and show that for the quaternion group of order 28, one of these presentations has non-standard second homotopy group.
