			The LMSFTW of length 7 is W1=(0,1,0,2,0,1,0) and the LMSFTW of length 8 is W2=
(0,1,0,2,0,1,2,0). Since the last term of W1 differs from the 7th term of W8, 7 is a term of the sequence.

			The LMSFTW of length 86 is (0,1,0,2,0,1,2,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,2,0,1,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,1,2,0,1,0,2,1,0,1,2,0,2,1,0,2,0,1,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,1,2,0,1,0,2,0,1), while the LMSFTW of length 87 is
(0,1,0,2,0,1,2,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,2,0,1,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,1,2,0,1,0,2,1,0,1,2,0,2,1,0,2,0,1,0,2,1,0,1,2,0,1,0,2,0,1,2,0,2,1,0,1,2,1,0,2,0,1,0,2). The last 6 terms of the former differ from the corresponding terms of the latter, whereas all previous terms are the same. Since 86 is the 5th term of A094672, we have a(5)=6.
