Brilliant idea, using "PI" and continue knitting the numbers as stripes.
I already saw some different ways to create the socks, two identical ones, or just following the numbers.
Since this pattern is easy, I just gave it a kick by firstly following the numbers which made irregular repeats, and secondly exchanging the colors.
That made two different socks on the first sight but on the second it matches.
