Yes, you have been introduced to Mr. Frobenius.

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**

I heard of the numbers before, but I could not recall them, let alone know that M has such an instruction.

M is like having a 1000 mathematicians as your personal pals. They will instruct you, just reading the help is an education!

**New Problem:**

**A standard deck has its cards turned over one by one. Where is the most likely spots for the 2 red jacks?**

**A says) All positions have the same chance by super - duper symmetry.**

**B says) Not exactly A. The best positions are...**

**C says) Quiet B, I have the answer. The best position for the two red jacks is the 24th and 25 card.**

**D says) What is position?**

**E says) I got it!**

**A says) We must have the same answer!**

**What do you get?**

Hi;

That is all I have. If it was not shuffled and was right out of the box it would be easy to determine the position of them.
