A digit block is a finite nonempty string of digits. For an integer base 
, let 
count occurrences of the block 
as consecutive digits in the base-
expansion of a positive integer 
, with no leading zeros. Overlapping occurrences
are counted separately. The following table gives 
for several binary blocks
