 Yes, true! I'll try to get this fixed.

 Here's what my Sage returns for this query:
 {{{
 matrix/operation_table.py:39:      * ``'letters'`` - lowercase ASCII
 letters are used
 matrix/operation_table.py:102:    The default symbol set for elements is
 lowercase ASCII letters,
 matrix/operation_table.py:768:          * ``'letters'`` - lowercase ASCII
 letters are used
 categories/groups.py:113:              * ``letters`` - lowercase ASCII
 letters are used
 categories/magmas.py:151:              * ``letters`` - lowercase ASCII
 letters are used
 categories/additive_magmas.py:123:              * ``letters`` - lowercase
 ASCII letters are used
 categories/additive_magmas.py:158:            elements as lowercase ASCII
 letters.  ::
 }}}

 Clearly, the first and third have been fixed. And, the second is of
 irrelevant nature.  Similarly, the last one. And, the other two required
 fix. I have fixed it.
