I thought I read an interview with Mclaren's senior aerodynamicist (the name escapes me) and in it he mentioned they are allowed to place as many elements on the front wing as they like, unlike at the rear. But he said the optimal solution is two or three elements.
Edit: here it is.

The front wing must not exceed 1400mm across, by 550mm deep and 200mm high. However, there is no limit on the number of aerofoils within that specified area – unlike the rear wing, which is restricted to two. “In theory,” says Doug, “we could run 30, 40 or even more elements. However, typically we fit just three and this can drop to as few as two for a low-downforce circuit, such as Monza in Italy.”
