The case for byte-savings can be made primarily for small sizes such as 1,2, and 4. OTOH, large numbers (say, up to 4096-bits) are useful for encoding cryptographic keys. Say, how about: 1-2-4-8-16-128-256-512 (2^x bytes) 0-1-2-3-4-7-8-9 (x: integers congruent to {0 1 2 3 4} mod 7) 1-2-4-8-16-256-1024-8192 (2^x bytes) 0-1-2-3-4-8-10-14 (x: integers s.t. 3^x+2 is a prime) 1-2-4-8-16-256-512-1024 (2^x bytes) 0-1-2-3-4-8-9-10 (x: integers s.t. x is a sum of at most 4 cubes) 1-2-4-8-32-128-2048-8192 (2^x) 0-1-2-3-5-7-11-13 (x: 0, 1, then integers s.t. x is a prime ) See http://www.research.att.com/~njas/sequences/ Best Regards, Rajesh
