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_67677 ( "Position" real, "Club" text, "Played" real, "Points" text, "Wins" real, "Draws" real, "Losses" real, "Goals for" real, "Goals against" real, "Goal Difference" real )

### Question ###
Which lowest position has goals against smaller than 78, Points of 42-2, and Wins larger than 15?

### Accurate SQL ###

SELECT MIN("Position") FROM table_67677 WHERE "Goals against" < '78' AND "Points" = '42-2' AND "Wins" > '15'
