How many RATO rockets of Swiss Mirage III？

[Blueking]

I have found some photoes that show 4 and 6 rockets be used .But one photo looks like one Swiss Mirage used 8 ones.

So，the max number is 8?

Standard was 8 rockets.
During the trials in Istres, France, configurations with 4, 6 and 8 rockets were tested. They even tested asymmetrical configurations with 5 and 7 rockets, because it could happen that some would not ignite.
