Equi-isoclinic subspaces from symmetry
Equi-isoclinic subspaces from symmetry
We describe a flexible technique that constructs tight fusion frames with prescribed transitive symmetry. Applying this technique with representations of the symmetric and alternating groups, we obtain several new infinite families of equi-isoclinic tight fusion frames, each with the remarkable property that its automorphism group is either $S_n$ or $A_n$. …
