Comments

Continued fraction expansion is 5 followed by {1, 10} repeated. - Harry J. Smith, Jun 04 2009

This is the length of the long leg of a right triangle with hypotenuse 6 and short leg 1. So this is half the length of the longest line segment that can be drawn within a circular ring with radii 6 and 1. - Michel Marcus, Jun 20 2020
