Can be bruteforced

[cmester0]

By the following code:

import keyboard
import time

pos = list(input())

keyboard.wait('space')

sleep_time = 0

def press(s):
    for c in s.lower():
        keyboard.press_and_release(c)
    time.sleep(sleep_time)
    keyboard.press_and_release("enter")


def iter_press(pos, depth, s = ""):
    if depth == 0:
        press(s)
    else:
        for i, a in enumerate(pos):
            iter_press(pos[:i] + pos[i+1:], depth-1, s+a)

for i in range(3, 6+1):
    iter_press(pos, i)
