Please check the signs in the docstrings. If they are all correct, then give this a positive review (or preferably, wait for patchbot to concur).

2f9048f  Spacing and other corrections

Oops, a few more doctest failures in src/sage/quadratic_forms/quadratic_form__genus.py
.

 Dependencies set to #23955
New commits:
88bdf3c  Fixed two bugs in the genus class

8e62210  Seems that is_2_adic_genus did not assume the input to be canonical but instead did not reduce the determinants mod 8. Changed that.

a7cf87e  Merge branch 'u/bhutz/projective_infinity' of git://trac.sagemath.org/sage into t/23376/equality_testing_of_genera_of_quadratic_forms_over_zz_changes_the_genus_and_produces_false_results

24a5b0b  Doctest formatting.

c4ced01  Merge branch 'u/sbrandhorst/equality_testing_of_genera_of_quadratic_forms_over_zz_changes_the_genus_and_produces_false_results' of git://trac.sagemath.org/sage into t/23916/pretty_printing_and_latex_for_genera_of_quadratic_forms

fda4bcd  Changed the printing representation to use the canonical symbol instead of the symbol. There is a bug in the compartments() method which prevents meaningfull doctest. We have to wait for that to be fixed first.

22c83b7  Rewrote canonical_2_adic_trains()

711bbf0  Removed unnecessary computations of compartments for the train function.

7dff05e  Resolved merge conflict in the doc tests

c3b136c  Adapted the doctests and modified them by hand where necessary

f81fb90  Cleanup in _latex_

I did check the signs in the docstrings. They are as intended now.

comment:19 Changed 2 years ago by
Patchbot is complaining about coverage. I think it's because the method _latex_
in genus.py
only has tests, whereas it should also have at least one example.
comment:20 Changed 2 years ago by
I guess we can make that an example instead.

I'm getting one doctest failure. Is this just a case where the output needs to be updated?
