 OFFSET 1,1 COMMENTS The representation of n given by A140116(n) is more compact than the standard binary form of n for these numbers consisting of a sufficiently large proportion of 0s or of 1s among their bits. LINKS EXAMPLE See also examples for A140116. 2180 is a term here as 2180 = 100010000100 (base 2), which uses 12 symbols, but A140116(2180) = 10112111210, which uses only 11 symbols including the two delimiter symbols (for which 2 is used).
