Dear all,

I've tried to compute Heilbronn Matrices for n=50000 in sage 5.4.1, but the following Error comes out when I run

sage: H=HeilbronnMerel(50000)

--------------------------------------------------------------------

RuntimeError Traceback (most recent call last)

/home/guests/sage-5.4.1/<ipython console=""> in <module>()

RuntimeError: Floating point exception

--------------------------------------------------------------------

It seems to be a bug in sage when computing Heilbronn Matrices for large n. However, I even couldn't find out why this happens. Anybody can please help me handle with that? Thank you.
