%N A105671 a(2n) = Lucas(2n+3)^2, a(2n+1) = Lucas(2n+1)^2.
%C A105671 This sequence is related to several other sequences on squares. In reference 
               to the link "Sequences in Context", (a(n)) = vessigcycseq. Note that 
               the identity "vessigcyc = jessigcyc + lessigcyc + tessigcyc" holds.
