2010-4-20 · Moreover, the TM sequence can also be generated by using the bit expansion of the position, that is, if i = ∑ j bj2 j, then ti = ∑ j bj (mod 2). So, T = (tn)n 0 counts the number of 1’s (mod 2) in the base-2 representation of n. A sequence has the nonoverlap property (also known as the BBb property) if the subsequence BBb, where B is a block of bits of any > 0 length, and b is the ﬁrst bit of B, does not appear in that sequence.
