  • Ticket #19251 – Description

    initial v12  
    1 Right now the .basis() methd returns the rows of a matrix, which naturally have no ambiant space and only the methods of `list`. This branch makes it an alias of `generator_matrix` (it used to be an alias of `.gens()`) so that this information remains available.
    2 
    3 Note that this matrix is also an iterable, and that one can as easily iterate on the rows of that matrix as on the elements of the list it previously returned.
     1Right now the `.basis()` method returns just a `list`. This should instead be an immutable `Sequence`, retaining the type information in its `.universe()` method.
