Paradox question tempted me to come to Sajha again! The two other ants that are in the front don't know if there are more ants behind the third ant since they never look back. However, they do know that there are two ants (i.e. themselves) in front of the third aunt. How's that, Paradox? Even if you give the credit of solving it, I am not going to make a politician, whatsoever. :) :D
