Table schema:
CREATE TABLE table_name_75 (loss INTEGER, avg_g VARCHAR, long VARCHAR, gain VARCHAR)

Question: What is the highest Loss, when Long is greater than 0, when Gain is greater than 484, and when Avg/g is greater than 126.4?
SQL: SELECT MAX(loss) FROM table_name_75 WHERE long > 0 AND gain > 484 AND avg_g > 126.4
