Intersection Numbers of the Natural Embedding of the Twisted Triality Hexagon T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$ in PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT In this paper, we study and characterise the natural embedding of the twisted triality hexagon T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$ in PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$. We begin by describing the possible intersections of subspaces of PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$ with T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$.

On Kotzig's Perfect Set Problem of Hamiltonian Cycle Decompositions of the Complete Graph

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamiltonian cycle decomposition (HCD) of K n ${K}_{n}$ is a set of Hamiltonian cycles in which each 1‐path of K n ${K}_{n}$ appears exactly once. A Dudeney set of K n ${K}_{n}$ is a set of Hamiltonian cycles in which each 2‐path of K n ${K}_{n}$ appears exactly once.

Transforming Solutions for the Oberwolfach Problem into Solutions for the Spouse‐Loving Variant

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT The Oberwolfach problem OP ( F ) $\mathrm{OP}(F)$, for a 2‐factor F $F$ of K n ${K}_{n}$, asks whether there exists a 2‐factorization of K n ${K}_{n}$ (if n $n$ is odd) or K n − I ${K}_{n}-I$ (if n $n$ is even) where each 2‐factor is isomorphic to F $F$. Here, I $I$ denotes any 1‐factor of K n ${K}_{n}$. For even n $n$, the problem OP( F ) $(F)

Understanding Autistic Young Adults' Perceptions and Experiences of Traumatic and Stressful Events

open access: yesJournal of Clinical Psychology, Volume 81, Issue 6, Page 445-461, June 2025.
ABSTRACT Objectives The aim of this study was to explore how young autistic adults experience and respond to stressful life events, and the relationship between autistic characteristics and symptoms of stress associated with these events. Methods Using an exploratory sequential mixed‐methods approach, an online qualitative survey was first administered
