Small circulant complex Hadamard matrices of Butson type
by GAURUSH HIRANANDANI AND JEAN-MARC SCHLENKER

The main paper is here. On this page you will find:
  • a python program used to find complete lists of equivalence classes of complex Hadamard matrices of rank n based on a l-th root of unity, for n and l small,
  • a pdf file containing the lists of circulant complex Hadamard matrices appearing in Table 1 of the paper.
  • a pdf file containing a description of the algorithm used in the python program above, and of the all the functions used in this program.
