If the row is dissimilar the end result is 1.

What happens when you increase the #vertical rows and apply various
combinations of 1's and 0's.
Let's try 5rows?

In XOR , if bit in a column is dissimilar result is 1. You do not add bit
row by row.

All vertical bits are checked XOR and if they are:
(0+0)=0
(0+1)=1
(1+1)=0
(1+0)=1

Hi Brian
I have the question regarding your paper on Computing Access-List and
Wildcard Pairs
There you have
00000000
00000100
00100000
00100100
_________
XOR
00100100=36****
I cannot get this trying in any way (for third column)
1) (((0 XOR 0) XOR 1) XOR 1)= ((0 XOR 1) XOR 1)= 1 XOR 1 =0
2) (0 XOR 0) XOR (1 XOR 1) = 0 XOR 0 = 0
I am doing something wrong or there is some other trick here ?
thanks
nenad
