On the two-distance embedding in real Euclidean space of coherent configuration of type (2,2;3)

Eiichi Bannai, Etsuko Bannai, Chin-Yen Lee +2

Finding the maximum cardinality of a $2$-distance set in Euclidean space is a classical problem in geometry. Lisoněk in 1997 constructed a maximum $2$-distance set in ${\mathbb{R}}^8$…
