[R] A little exercise in R!

A recent news item got me thinking that a problem stated
therein could provide a teasing little exercise in R
Cambridge University hosts first European 'maths Olympiad'
The first European girls-only "mathematical Olympiad"
competition is being hosted by Cambridge University.
Olympiad co-director, Dr Ceri Fiddes, said competition questions
encouraged "clever thinking rather than regurgitating a taught
"A lot of Olympiad questions in the competition are about
proving things," Dr Fiddes said.
"If you have a puzzle, it's not good enough to give one answer.
You have to prove that it's the only possible answer."
"In the Olympiad it's about starting with a problem that anybody
could understand, then coming up with that clever idea that
enables you to solve it," she said.
"For example, take the numbers one up to 17.
"Can you write them out in a line so that every pair of numbers
that are next to each other, adds up to give a square number?"
Well, that's the challenge: Write (from scratch) an R program
that solves this problem. And make it neat.
NOTE: If there should happen to be some R package that can solve
this kind of problem already, without you having to think much,
then its use is illegitimate! (I.e. will be deemed "regurgitation").
Over to you.
With best wishes,
