We calculate the spectrum of the diagram for each finite 3-transposition group. Such graphs with a given minimum eigenvalue have occurred in the context of compact Griess subalgebras of vertex operator algebras.

In this paper, we will prove that for shaped binary sequences, the central SRS and SHG contrast ratios are closely related to the traditional Merit Factor values. And in light of known results in Merit Factor Problems, we have constructed binary sequ

In an earlier paper, the first two authors found all distance-regular antipodal covers of all known primitive distance-transitive graphs of diameter at least 3 with one possible exception. That remaining case is resolved here with the proof that a pr

In this note we give an overview of our knowledge regarding primitive axial algebras of Jordan type half and connections between $3$-transposition groups and Matsuo algebras. We also show that primitive axial algebras of Jordan type $\eta$ admit a Fr

Nonassociative commutative algebras $A$ generated by idempotents $e$ whose adjoint operators ${\rm ad}_e\colon A \rightarrow A$, given by $x \mapsto xe$, are diagonalizable and have few eigenvalues are of recent interest. When certain fusion (multipl

We describe the structure, including composition factors and submodule lattices, of cross-characteristic permutation modules for the natural actions of the orthogonal groups O m ± ( 3 ) with m ≥ 6 on nonsingular points of their standard modules. T

We study the odd-characteristic structure of permutation modules for the rank 3 natural actions of O 2 n ± ( 2 ) ( n ⩾ 3 ) and U m ( 2 ) ( m ⩾ 4 ) on nonsingular points of their standard modules.

The known families of binary sequences having asymptotic merit factor 6.0 are modifications to the families of Legendre sequences and Jacobi sequences. In this paper, we show that at N = pq, there are many suitable modifications other than the Jacobi

Based on the third author's thesis ( arXiv:0805.2403 ) in this article we complete the local recognition of commuting reflection graphs of spherical Coxeter groups arising from irreducible crystallographic root systems.
