Suppose you a list of alphabets A,B,C,......Z and another list of numbers from 1,2,.....10

How many ways can you combine the above two lists into a single list? The constraint is after mixing partial order between alphabets, and partial order between numbers should still be retained?

That is A should always come B, and B before c.......

and 1 before 2,,,2 before 3........ so on
