Reciprocal of 89/Mistake

$89$

Mistake

$89$ is the $11$th Fibonacci number, and the period of its reciprocal is generated by the Fibonacci sequence: $1 / 89 = 0 \cdotp 11235 \ldots$

Correction

That should read:

$1 / 89 = 0 \cdotp 01123 \, 5 \ldots$

This mistake is corrected in the Curious and Interesting Numbers, 2nd ed. of $1997$.
