A024803: misprints and Q

[franktaw at netscape.net]

Numbers that are not the sum of 3 squares are those of the form 
(8m+7)*4^k, which means that most (3/4) of them are odd.  Requiring 
distinct and non-zero squares obscures this consideration, but it is 
the dominant one for large n.

BTW I have a Q:
if we look for numbers absent in A024803 (or in
A004432) we'll meet odd numbers more often than even
ones - any explanation?
