Cyclic p-roots of prime lengths p and related complex Hadamard matrices
Uffe Haagerup
In this paper it is proved, that for every prime number p, the set of cyclic p-roots in C^p is finite. Moreover the number of cyclic p-roots counted with multiplicity is equal to (…

All cyclic p-roots of index 3, found by symmetry-preserving calculations
Goran Bjorck, Uffe Haagerup
When using a Groebner basis to solve the highly symmetric system of algebraic equations defining the cyclic p-roots, one has the feeling that much of the advantage of computerized…
