Status: Reported

Section Appendix A says:

# section A.1 sage code:

       for A in xrange(3, int(1e9)):
           if (A-2) % 4 != 0:
             continue

# section A.3 sage code:

       for uInt in range(1, 1e3):
         u = F(uInt)

It should say:

# section A.1 sage code:

       for A in xsrange(3, int(1e9)):
           if (A-2) % 4 != 0:
             continue

# section A.3 sage code:

       for uInt in xsrange(1, int(1e3)):
         u = F(uInt)

Notes:

"xrange" is not recognized by Sage with python 3, so the script from section A.1 fails with a syntax error (using "xrange" likely worked fine for Sage with python 2). The suggested changes in A.3 are just for consistency.
