Hi, all, I'm looking for a kind soul to check the fix for #10741, which deals with left/right matrix actions on binary quadratic forms (in BinaryQF). The code, as it is now, does not produce an associative action, i.e., Q.matrix_action_right(M).matrix_action_right(N) != Q.matrix_action_right(M*N) and similarly for the left action.
The fix is simple (just swap the choice of matrix elements used in each case: columns for right action, rows for left). I'm willing to condone a modest level of bribery :-} Justin -- Justin C.
