%C Numbers that are sums of distinct powers of 100. - _David Wasserman_, Feb 26 2008

%F a(n)=A062033(n)/10 i.e. with final zero removed.

%F a(n)=Sum_k>=0 {A030308(n,k)*A098608(k)}. - From _Philippe DelĂ©ham_, Oct 15 2011.

%F G.f.: (1/(1 - x))*Sum_{k>=0} 100^k*x^(2^k)/(1 + x^(2^k)). - _Ilya Gutkovskiy_, Jun 04 2017

%e a(11)=1000101, since 11 in binary is 1011 and binary carryless sum of 1011000, 0, 10110 and 1011 is 1000101.

%Y Cf. Moser-de Bruijn sequence A000695, carryless decimal squares A059729, pre-carry binary squares A063009.
