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.
