+## Functions constructing generators of maximal subgroups
+- [ ] The code which computes and then stores the sizes is correct. To do this one confers to the tables referenced by the code. Tests for the group size should use `RECOG.TestGroup` from the recog package.
+- [ ] The test suite checks whether all constructed generators are sensible. That is it tests the generators'
+  - [ ] determinants (and if applicable also the spinor norms are correct), and
+  - [ ] compatibility with the correct form.
+
+## Functions assembling the list of all maximal subgroups of a certain group
+The code agrees with the tables in section 8.2 of the book "The Maximal Subgroups of the Low-dimensional Finite Classical Groups".
+
+The reviewer doesn't need to compare our results to magma's results. That's the job of the person implementing the code.
