Generating wordlist using specific charlist with exclusions

[Kangaroot]

Not pretending to be unique in my inquiry, but I have specific task to do. How can I generate word list using specific char list and applying multiple rules or exclusions?

For example:

Charlist = ?l?l?l?l?l?l?l?l
Rules/Exclusions:

• each character cannot appear more than 3 times
• no 3 characters in a row can be identical
• no 3 characters in a row can be sequential (abc)
• no 3 characters in a row can be reverse sequential (cba)
• character 2 is not equal to character 1
• character 2 is not +1 to character 1
• character 2 is not +2 to character 1

Please advise!
