XOR
An operation in Logic known as Exclusive Or. It yields true if exactly one (but notboth) of two conditions is true. The Binary XOR operator has the followingTruth Table.
 |  | XOR |
| F | F | F |
| F | T | T |
| T | F | T |
| T | T | F |
The Binomial Coefficient 
mod 2 can be computed using the XOR operation
XOR 
, making Pascal's Triangle mod 2 very easy to construct.
