Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: 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?

### Accurate SQL ###

SELECT MIN(number__map_) FROM table_name_71 WHERE area_in_km² = 9.7 AND population_canada_2011_census > 66 OFFSET 158
