:In the Go program, I took advantage of Shyam's observation that no rare number up to 10^20 ended in 3. So, as far as the 21 digit numbers are concerned, a possible fly in the ointment is that they could in theory end in 3 (with a first digit of 8) which would, of course, mean adding another key/value pair to the 'fml' dictionary with other consequent amendments. The chances are that there won't be any such numbers but you might want to bear it in mind if you have occasion to run this instance again.

:As far as the 20 digit numbers are concerned, there shouldn't be any issues if you're running a BigInteger version for that too and adjusting the IsSquare method accordingly.
