I found the article on Heaviside an interesting read.

The 13th roots were pretty interesting. What I want to know is what the 500-digit number was that Wim Klein calculated the 73rd root of in 1976. Anyone know where I can find the original number or its root? All I know is that the root is between 6848830 and 7068302, and I can't seem to find a site to read the book (Guinness Book of World Records 1976) online.

According to this , it was a 507 digit number, which puts the root between 8540964 and 8814658 inclusive.

This article says it has pictures of the 73rd root demonstration. I think the top picture is the 500+ digit number, so you can probably work out the number even though some digits are cropped out.
