[seqfan] Re: A032355 extension

Comparing the parity of A032355 with your additional terms, to the parity of
A171956 I briefly thought I was on to something, alas later terms don't
match :-)

A032355 ,1,0,0,1,0,1,0,1,1,1,1,1,0,0,0,1,0,1,0,0,1,1,0,1,0,1,0,1,0

(N=640), though not in a super-convenient format.
