Comment(by unknown (google)):

 I removed the theta_table and added a fuzz test.  This uncovered a
 problematic (A, E) pair which I moved into its own test.  I looked through
 the code for typos, but I couldn't find any; the buggy path would be the
 long pade order 13.  I also checked this particular (A, E) against R
 expmFrechet as a black box, and they don't show this bug.  So it's
 probably a typo that I somehow can't see.  I also tried not being clever
 with LU decomposition but this didn't help.
