Hi,
There is a bug in hyperbolic_polygon which happens quite rarely, but for
example
l = [-1, 1, -0.0571909584179366 + 0.667*I]
hyperbolic_polygon(l, model='PD')
results in an incorrectly drawn hyperbolic triangle. It seems to be a
subtle numerical issue; if the last element
ribing the things you

Hi,
I think sometimes matrices over QQbar give erroneous results (sorry for the
messy example, if I try to simplify it the problem disappears):
R. = QQ[]
v1 = QQbar.polynomial_root(AA.common_polynomial(y^2 + 1), CIF(RIF(RR(0)),
RIF(-RR(1
v2 = QQbar.polynomial_root(AA.common_polynomial(y^2 + 1
