• What the plain should be:
  Hello9, Hell9o, Hel9lo, He9llo.....9Hello

2)

• Word in the wordlist: Hello
• Chosen set of digits: { 9, 1, 8 } and chosen permutation maxcombination with this set: 2 ( 11,18,19,81,91,88,99,89,98)
• What the plain should be:
  Hello19, Hell19o, Hel19lo, He19llo.....19Hello
  Hello11, Hell11o, Hel11lo, He11llo.....11Hello
