In this paper, we construct some codes that arise from generalized hexagons with small parameters. As our main result we discover two new projective two-weight codes constructed from two-character sets in PG(5,4) and PG(11,2). These in turn are constructed using a new distance-2-ovoid of the classical generalized hexagon H(4). Also the corresponding strongly regular graph is new. The two-character set is the union of two orbits in PG(5,4) under the action of L2(13). 
On the Hall-Janko graph with 100 vertices and the near-octagon of order (2, 4)
In this paper, we construct the Hall-Janko graph inside the split Cayley hexagon H(4). Using this construction, we then embed the near-octagon of order (2,4) as a subgeometry of the dual of H(4),
Ovoids and spreads of finite classical generalized hexagons and applications
One intuitively describes a generalized hexagon as a point-line geometry full of ordinary hexagons, but containing no ordinary n-gons for n<6. A generalized hexagon has order (s,t) if every point is
Some two-character sets
Some new examples of two-character sets with respect to planes of PG(3, q2), q odd, are constructed. They arise from three-dimensional hyperbolic quadrics, from the geometry of an orthogonal polarity

The geometry of some two-character sets
A projective (n, d, w1, w2)q set (or a two-character set for short) is a set $${\mathcal{S}}$$ of n points of PG(d − 1, q) with the properties that the set generates PG(d − 1, q) and that every
Embeddings of Un(q2) and symmetric strongly regular graphs
In the geometric setting of the embedding of the unitary group Un(q2) inside an orthogonal or a symplectic group over the subfield GF(q) of GF(q2), q odd, we show the existence of infinite families
Regular partitions of (weak) finite generalized polygons
TLDR
A structural investigation on the substructures of finite generalized polygons and unifying, alternative and more elegant proofs of the results in Offer are given.
Three-qubit operators, the split Cayley hexagon of order two, and black holes
The set of 63 real generalized Pauli matrices of three-qubits can be factored into two subsets of 35 symmetric and 28 antisymmetric elements. This splitting is shown to be completely embodied in the
