Then that is proof of ESP.

Were you also thinking about a big corned beef sandwich? No? Neither was I! Another amazing coincidence or...

I meant to say that I think me were thinking about the sane thing in posts #42 and #43.

I'd say that's the same thing I said.

Diagonalization?

There is an interesting little idea in Computer math that might help.

What if you had a grid 100 by 100. You would need to get th 100th power of a 10201 by 10201 matrix!

Hohohohohohohoo! That is a good one! I just talked to Mathematica and he said it sure is. Also there are ways to just get one element of that matrix!

I'm not sure if getting the 8th piwer if a huge matrix is fast.

The matrix can be filled by a program as the "Dice" guy does. Also it is a lot easier for a computer to do.

It takes much londer if you have a larger grid. I'd say DP is better here.

WWHD? Why Would Hay Decompose?

Now run

MatrixPower[A, 8][[1]]

the last entry means from 1 to 24, 38 ways.
