Description (last modified by gh-aodesky)

Implement a method which returns the ramification type of a rational function. The ramification type is a list of lists of positive integers >0 defined by the pseudo code

def ram_type(self):

ram_types=list() for b in self.branch_points():

ram_inds=list() for c in F.preimage(b)

ram_inds.append(c)

ram_types.append(ram_inds)

return ram_types
