Table schema:
CREATE TABLE table_name_61 (byes INTEGER, draws VARCHAR, against VARCHAR, losses VARCHAR)

Question: What is the highest value for Byes, when Against is less than 1794, when Losses is "6", and when Draws is less than 0?
SQL: SELECT MAX(byes) FROM table_name_61 WHERE against < 1794 AND losses = 6 AND draws < 0
