Title: License plates
Post by mkaraki on Jan 9^th, 2010, 4:40pm

I searched before posting but I didn't find any reference. Anyways here is the riddle:

A state wants to issue 6-digit license numbers, with the digits from 0 to 9. If every number has to differ from every other number in at least 2 places, what is the maximum number of licenses that it can issue?

The default setting only searches up to a year in the past; but it has been posted before that time, here (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_medium;action=display;num=1211349162).
