Code:
13(666(666+666)*(666+13*(13+13)))/666 Assuming that we would use "only" the +,,*,/ operations (no other crazy . or concat) and no large (intermediate) numbers.

I've proven by brute force search that there does not exist a solution using either 7 numbers or 4 of each, if we only allow the simple operators +, , *, /.
The closest solution with 4 of each is 13 + 13 + 666 + 666 + 666  666/(13*13) = 2020.05917...

2020 = 666 + 666 + 666 + sqrt(666  13*13  13)
7 numbers.
