Thanks. Now why didn't I reflexively check the OEIS for the sequence:
4, 484, 28224, 228484, 8282884?
But for purposes of this problem we need those squares all of whose digits
are a subset of {2,4,8}.
The sequence
http://www.research.att.com/~njas/sequences/table?a=18885&fmt=4
of squares made with only 2 distinct digits might also be useful. --I see
that David was the author of that sequence.
