I've concatenated words of length 3 to obtain a digit sequence of zeros and ones which I have defined as shown
u := 00001010011000001010011000001010011000001010011000001010011000001\
0100110000010100110000010100110000010100110000010100110000010100110000\
0101001100000101001100000101001100000101001100000101001100000101001100\
00010100110000010100110000010100110
Now I want to index each digit, that is, the sequence (u_i):= u_0u_1u_2u_3 ... so that I can sum (u_i)z^i from i=0 to infinity, followed by sum (u_{i+1})z^i from i=0 to infinity, ...
sum (u_{i+n})z^i from i=0 to infinity.
I wonder if someone can help me with the syntax to give each digit of u an index as required.
Here's hoping. thanks, sheila
ps thanks for answering my last post about plotting  still trying.
