Thin divisible designs graphs: an interplay between fixed-point free involutions of -graphs and symmetric weighing matrices
Sergey Goryainov, Willem H. Haemers, Elena V. Konstantinova +1
In this paper, we illustrate important aspects of the interplay between weighing matrices, -graphs with fixed-point free involutions, and signed graphs with an orthogonal…

Generating the symmetric group by three prefix reversals
Saúl A. Blanco, Mikhail P. Golubyatnikov, Elena V. Konstantinova +2
The cubic pancake graphs are Cayley graphs over the symmetric group generated by three prefix reversals. There is the following open problem: characterize all the…
