User talk:74.62.253.117

Based on the characteristic kind of disruptive edit to P versus NP problem you did, as well as matching IP location, I strongly suspect that you are the same user as 76.168.249.213, who is currently blocked for this behaviour. Note that evading blocks by using different accounts or IPs is prohibited on Wikipedia as sock puppetry.—Emil J. 10:23, 5 May 2010 (UTC)
