[seqfan] Re: Can more of these terms be found?

[Allan Wechsler]

"Numbers whose decimal form can be split into two parts, the square of
whose difference is the original number." Is that too long? My concern is
the ambiguity of the phrase, "split into two parts".

Or ... "Numbers of the form K 10^n + L, L<10^n, that are equal to (K-L)^2."
