I looked at the book ^[1]. There's nothing about "Egyptian fractions 31/311" in it. Need to be reassured. -- Smartsl ( talk) 09:59, 18 September 2019 (UTC) reply

It's Third Edition though. Maybe the wrong one. -- Smartsl ( talk) 10:17, 18 September 2019 (UTC) reply

Odd that it would have been removed, but it's definitely in my print copy of the first edition. More specifically, on 273, it has "Exercise: What is the greedy representation of 31/311? (There are 10 terms, the last of which has a denominator with over 500 digits!)" — David Eppstein ( talk) 19:13, 18 September 2019 (UTC) reply
