Default I guess this is OPN-related

factordb.com suggests that (n^61-1)/(n-1) has been carefully factored for all n<1000, though rather neglected above that value. I wonder why that was done?

See here: http://www.asahi-net.or.jp/~KC2H-MSM/cn/index.htm
These tables goes up to exponent=1000. Btw do you know why there is no update in the last roughly 3.5 years? (the homepage is at http://www.asahi-net.or.jp/~KC2H-MSM...tha1/index.htm)
