Table schema:
CREATE TABLE table_name_71 (number__map_ INTEGER, area_in_km² VARCHAR, population_canada_2011_census VARCHAR)

Question: Which Number (map) is the lowest one that has a Area in km² of 9.7, and a Population Canada 2011 Census larger than 66,158?
SQL: SELECT MIN(number__map_) FROM table_name_71 WHERE area_in_km² = 9.7 AND population_canada_2011_census > 66 OFFSET 158
