%N The Fibonacci word in A104324 partitioned into blocks.
%C This way of representing the block structure of A104324 is used by Zhang et al. (2017), but of course only makes sense for blocks 0 through 9.

%e The initial blocks are as follows:
%e 0,
%e 1,
%e 22,
%e 323,
%e 42344,

%e but if the commas are inserted (as they should be) then we see the blocks more clearly:
