     1This ticket organizes various improvements in order to get faster matrices over cyclotomic fields. The aim is to implement and compare three different ways to perform such computation:
     2
     3- libgap wrappers
     4- generic matrix (`matrix_generic_dense.Matrix_generic_dense`)
     5- the specialized inadapted class that is used by default now in Sage (`matrix_cyclo_dense.Matrix_cyclo_dense`)
