For example, fuse(1)=3, for 9/8 = 1 + 1/(2^fuse(1)). Over 2 minutes, time(2) = 2 + 1/(2^fuse(2)) = 2049/1024 minutes. The value for fuse(3) is larger than 2↑↑↑↑↑↑↑↑↑16, in Knuth's up-arrow notation. - _Ed Pegg Jr_, Apr 03 2011; edited by _Junyan Xu_, Jan 04 2012 %H A188545 Jeff Erickson, <a href="http://www.mathpuzzle.com/fusible.pdf">Fusible Numbers</a>, 2010.
