awk if statement checking multiple arrays -

i have file this:

1 1 9 2 2 4 3 2 5 4 2 4 

i want awk print unique records based on second , third field. both fields must unique printed.

the ideal output this:

1 1 9 2 2 4 3 2 5 

so record 4, because identical record 2, left out.

this tried:

cat file | awk ' !($2 in array) && !($3 in barry) { array[$2]; barry[$3]; print}' 

running command results in:

1 1 9 2 2 4 

so doesn't add record 3 because it's second field identical record 2's.

how go coding awk checks both values?

this should do:

awk '!a[$2,$3]++' file 1 1 9 2 2 4 3 2 5
