When at Wikisources [[Pi to 1,000,000 places]] an anonymous user changes the first 10 digits of line 14320 from "0628419546" to "1516171819" how is anyone possible able to know which is correct? :-) :'(
The obvious thing to do would be to revert it. The chances that the anonymous user knew pi to 1,000,000 decimal places and noticed the error are pretty small. The regularity of the sequence "1516171819" should be a giveaway, just like the sequence inserted in the same edit on the previous line "1234567890".
That said, a google search turned up a site apparently made for precisely this problem:

Not that it matters, you only need tens of digits to solve any conceivable physical problem. What a waste of disk space.
Thanks to all of you who responded on this. The only useful value for the the article that comes to mind is as a convenient long list of pseudo-random numbers when somebody needs one. Beyond that, the love that some people have for this sort of thing gives a fantastic insight into their characters.
Thanks for catching the sequence; I should have noticed it myself.
I've reverted the vandalism and protected the page. That seemed the simpler option. I didn't really want to get into a fight about deleting this; I get enough fights already.
