On the spherical design properties of a $P$ - and $Q$ -polynomial association scheme

Jesse Lansdown, William J. Martin, Akihiro Munemasa +2

We show that the strength as a spherical design of the spherical embedding of a $P$ - and $Q$ -polynomial association scheme with at least three classes with respect to a $Q$ -polynom…

Sets of equiangular lines in dimension $18$ constructed from $A_{5}^{3} \oplus A_{1}^{4}$

Akihiro Munemasa, Ferenc Szöllősi, Kiyoto Yoshino

In 2023, Greaves, Syatriadi, and Yatsyna found a set of $57$ equiangular lines in $R^{18}$ , breaking the previous record. In 2025, Lin, Munemasa, Taniguchi, and Yoshino co…
