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_75418 ( "Rank" text, "City" text, "Population" real, "Area (km 2 )" real, "Density (inhabitants/km 2 )" real, "Altitude (mslm)" real )

### Question ###
Which Population is the highest one that has a Density (inhabitants/km 2) larger than 2805.8, and a Rank of 1st, and an Altitude (mslm) smaller than 122?

### Accurate SQL ###

SELECT MAX("Population") FROM table_75418 WHERE "Density (inhabitants/km 2 )" > '2805.8' AND "Rank" = '1st' AND "Altitude (mslm)" < '122'
