I have Sage 4.1.1 install on a server, and I run the following code, which outputs the following error:
sage: A3=SteenrodAlgebra(3) sage: A3.P(36,6)*A3.P(27,9,81) --------------------------------------------------------------------------- KeyError Traceback (most recent call last) /home/user_bob/<ipython console> in <module>() /usr/local/sage-4.1.1/local/lib/python2.6/site-packages/sage/structure/ element.so in sage.structure.element.RingElement.__mul__ (sage/ structure/element.c:9956)() /usr/local/sage-4.1.1/local/lib/python2.6/site-packages/sage/structure/ element.so in sage.structure.element.RingElement._mul_ (sage/structure/ element.c:10021)() /usr/local/sage-4.1.1/local/lib/python2.6/site-packages/sage/algebras/ steenrod_algebra_element.pyc in _mul_(self, other) 925 new_dict = milnor_multiplication (mono1, mono2) 926 else: --> 927 new_dict = milnor_multiplication_odd (mono1, mono2, p=p) 928 for new_mono in new_dict: 929 if result.has_key(new_mono): /usr/local/sage-4.1.1/local/lib/python2.6/site-packages/sage/algebras/ steenrod_milnor_multiplication_odd.pyc in milnor_multiplication_odd (m1, m2, p) 225 t = tuple(diagonal[:i+1]) 226 if result.has_key((e,t)): --> 227 result[(e,t)] = F(coeff + result[t]) 228 else: 229 result[(e,t)] = F(coeff) KeyError: (26, 8, 86) sage: I have had a similar errors on older versions of sage and on different computers. Letting Ap=SteenrodAlgebra(p), I also have errors running A5.P(25,75)*A5.P(125,15,105) A7.P(49,126)*A7.P(343,21,777) A11.P(11*200,11*15)*A11.P(11^5,44,11*20) Notice that each entry is a multiple of the prime. I don't know if that has anything to do with it. Has anybody else encountered this error? How would one go about fixing it?
