%N Squares written in base 11. (Next term contains a nondecimal digit.)
%C From _Michael De Vlieger_, Nov 13 2014: (Start)
%C The next term contains a nondecimal digit: see the link below for an expanded table of squares with the nondecimal digits.
%C As n increases, a(n) cycles through the end digits in the order 0, 1, 4, 9, 5, 3, 3, 5, 9, 4, 1.
