That sounds plausible. Could there be a reason for having more than one thumb per hand?
As it was a year after I typed this topic it was kind of tough to remember exactly what I wrote although I did read back over what I said and I noticed that I did not say that a 4d hand would have more than one thumb just more than one finger as indicated by what I said here.
4d hands would probably still only need 2 sets of fingers to get a good grip.
Bye the way, what's the story behind the red and blue A's?
Oh yea the red and blue A's in my signature are there to represent a mathematical pattern that is similar to the pattern of prime numbers in the sense that there is no (known) natural process that can specifically produce that pattern of numbers. The blue A's are to represent the numbers that can be rooted by another other than one whole number to get a whole number. The pattern includes the numbers 1, 4, 8, 9, 16, 25, 27, 32, and so on. Basically if you take a number and try rooting it by some of the lesser whole numbers and when one or more of it's whole number roots equals another whole number it will be represented by one of the blue A's in my signature so long as it's lesser than the total number of A's in my signature. So because any root of one is one the first A of my signature is blue, because the square root of four is two the fourth A of my signature is blue, because the third root of eight is two the eighth A in my signature is blue, because the square root of nine is three the ninth A in my signature is blue, because the square root of sixteen equals four and the fourth root of sixteen equals two the sixteenth A in my signature is blue, because the square root of twenty five equals five the twenty fifth A in my signature is blue, and so on. The A's in my signature also extend beyond what you can see of them on the screen and using this information you can figure out were the next blue A's of my signature are.
