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.

First,
by permitting the double factorial
46 = (3!)!!  SQRT(4) and
50 = (3!)!! + SQRT(4).
51 = (3!)!! + 4  1
52 = (3!)!! + 4
53 = (3!)!! + 4 + 1
54 = (3!)!! + (4  1)!
55 = (3!)!! + 4!!  1  or 4! + 31
56 = (3!)!! + 4!!
57 = (3!)!! + 4!! + 1  or, as subfactorials are permitted 
(3!)!! + !4
58 = (3!)!! + !4 + 1
A solution exists for 60 to 65, but one was not found for 59, which may not have a solution with the given operators. Thus 58 may be as high as one can go. {Primes are difficult the higher one goes.}
