%N For each term n in this sequence, both n and n+1 can expressed as sum of three distinct nonzero squares in 2 or more ways

%e Considering the term 149, 149 = 1^2+2^2+12^2 = 2^2+8^2+9^2 = 6^2+7^2+8^2 and 150 = 1^2+7^2+10^2 = 2^2+5^2+11^2

%Y Subset of A024804, any A024804(n) is contained in this sequence if A024804(n)+1=A024804(n+1)

%K nonn

%O 1,1
