The problem of the representation
N = a/b + b/c + c/a
with a,b,c integers ( not necessarily positive )
is discussed in the paper
TWO MORE REPRESENTATION PROBLEMS
by Andrew Bremner and Richard Guy
published in Proc. Edinburgh Math. Soc. vol 40 1997 pp 1-17.
N = 62 and N = 64 both have solutions but they are quite large.
