it first appeared in A. Cyril Pearson’s 1907 20th Century Standard Puzzle Book
(London). But its' mathematical underpinnings have been traced back to Nicomedes
(~200 BCE), as well as to Newton (1720) and Thomas Simpson (1745).
The problem ... is just one in a group of 'ladder' problems

A solution is presented at Shortest Ladder Problem
