Hello,
The actual issue was that I forgot to covert symmetrica's LONGINT type
( 22 ) over to the correct Sage type. I hadn't actually tested it
with calculations that got up to numbers that big. I made a ticket
for this and posted a patch: http://sagetrac.org/sage_trac/ticket/1445
It will be
That was fast!
Thanks for looking into the problem. I'll be doing more extensive
calculations over the next couple of weeks (I'm porting some Maple
code). I'll let you know if I run into any other problems. I'm excited
about the prospect of a 17-fold performance increase.
Thanks very much,
