Given four digits 1,2,3 & 4 you are asked to create all integer numbers from 1 to 150 using some or all of those digits and the following operations: concatenation (numbers only), +-/*^! and sqrt plus any amount of brackets. No other operators, no subfactorials, no double factorials, logs etc

For any correct result score +1 point. If for a certain number no answer was found the penalty is -6 points if the the missing answer is between two valid solutions
or -8 otherwise.
Partial results accepted and the final answer will be the updated list. Examples: 123 = 123; 6= 3!; 88=(43+1)*2.

REM1: Use software only for difficult cases, most of the work is easily done by hand
REM2: If facing several valid choices ,- choose the simplest.

Have fun !
