Neil, Clark, seqfans,

there are  misprints in A024803:
both 105 and 122 should  be twice because: 
105=1^2+2^2+10^2=4^2+5^2+8^2, and
122=3^2+7^2+8^2=4^2+5^2+9^2.
Zak

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?
Thanks, Zak
