1997: David Wells: Curious and Interesting Numbers (2nd ed.):

The Dictionary

$\paren {11^{104} + 1} / \paren {11^8 + 1}$

Mistake

Equal to $86,759,222,313,428,390,812,218,077,095,850,708,048,977$ $\times$ $1,084,881,048,536,374,706,129,613,998,429,729,484,098,346,115,257,905,772,116,753$.

Incorrect.

The second factor is in fact:

$108 \, 488 \, 104 \, 853 \, 637 \, 470 \, 612 \, 961 \, 399 \, 842 \, 972 \, 948 \, 409 \, 834 \, 611 \, 525 \, 790 \, 577 \, 216 \, 753$

David Wells cites 1989: Paulo Ribenboim: The Book of Prime Number Records (2nd ed.) for this result, so it is possible that this is where the mistake originates.
