The resulting sequence from the definition above should be
A193800 Least m > 0 such that (n+m)^2 - m^2 (= n^2 + 2*m*n) is a square.
However, similar definitions are
A055527 Shortest other leg of a Pythagorean triangle with n as length of
a leg.
and the recent:
A242219 Smallest a(n) in Pythagorean triple (a, b, c) such that c(n) -
b(n) = n.
