@acer Thank you! That was helpful.

A follow up question

I have a decimal number, for ecample 0.04572.

How can I find out the number of its decimal digits? Here it would 5.

## Thanks!...

@MapleMathMatt I solved the problem with your help. Thank you very much!

## other elements not all different from N...

@Kitonum Thank you, very kind. My problem is, that in my lists L usually not all other elements differ from the elements in N; my lists L look like L1 and L2 in my examples. How could I solve that problem?

## Yes!...

@MapleMathMatt Thats it! Thank you very much! Very impressing :)

## second option...

@MapleMathMatt It is the goal to take a given number and see if it can be recreated from the legtover digots.

## repeats...

Thanks a lot. My example was not good. The repeats should not removed all. And then with the remaining digits in p' and q' should be checked, if another given number s and t can be created.

A better example is: p=245266, q=526676. Is it possible, with the remaining digits of p' to create the number s=42? And with the remaining digits of q' to create the number t=66?

p and q have the digits 2, 5, 6, 6 in common. For p' remain 2 and 4, for q' remain 6 and 7. So, The number r= 42 can created from 2 and 4, but not t=66 from 6 and 7.

Sorry for the circumstances!

Thank you very much.
