Half of an antipodal spherical design

Eiichi Bannai, Da Zhao, Lin Zhu +2

We investigate several antipodal spherical designs on whether we can choose half of the points, one from each antipodal pair, such that they are balanced at the origin. In particul…

Spherical embeddings of symmetric association schemes in 3-dimensional Euclidean space

Eiichi Bannai, Da Zhao

We classify the symmetric association schemes with faithful spherical embedding in 3-dimensional Euclidean space. Our result is based on previous research on primitive association…
