Let us use the first 3 digits of PI, i.e.
3,1,4 to create numbers from 1 to 50, using only basic math. operators.
Not all the digits must be used, but none can be repeated.
Examples (out of this range):
52= 13*4; 65=4^3+1; 84=14*3!
Only few numbers cannot be achieved.
Please show your list.

I limited my solutions with (!) to subfactorials, factorials, and double factorials [and the initial given operations to the puzzle].
One can get quite far with the three numbers (there is a finite limit, though) using multifactorials in addition to the given operations. As an aid to values between 1 and 100  only using the number 4 with the given factorialtype functions:
1 = !(SQRT(4))
2 = SQRT(4)
3 = SQRT((!4))
4 = 4
6 = (SQRT(!4))!
8 = 4!!
9 = !4
16 = (4!!)!!!!!
18 = (!4)!!!!!!
24 = 4!
27 = (!4)!!!!!
32 = (4!!)!!!!
36 = (!4)!!!!
45 = (!4)!!!
48 = (SQRT(!4)!)!!
54 = (((SQRT(!4))!)!!!)!!!!!!!!!!!!!!!
60 = ((SQRT(!4)!)!!!!)!!!!!!!
64 = ((4!!)!!!!!)!!!!!!!!!!!!
72 = (((SQRT((!4))!)!!!!)!!!!!!
80 = (4!!)!!!
90 = (((SQRT(!4))!)!!!)!!!!!!!!!!!!!
96 = ((4!!)!!!!!)!!!!!!!!!!
With the 1 and 3 available, with addition and subtraction (and 3!) to fill in the gaps between of following those numbers, one see that one can reach and surpass 100 with the three digits.
