Schema: CREATE TABLE table_name_24 (byes INTEGER, against VARCHAR, mininera_dfl VARCHAR, wins VARCHAR, losses VARCHAR)
Question: WHAT ARE THE BYES WITH A WIN SMALLER THAN 16, 8 LOSSES, AND AT PENSHURST, WITH AGAINST SMALLER THAN 1405?
SQL: SELECT SUM(byes) FROM table_name_24 WHERE wins < 16 AND losses = 8 AND mininera_dfl = "penshurst" AND against < 1405
