Hi.  I am looking for advice on shortening my compression technique's Huffman code header.  I do the following to shorten such:

*  A repeated value takes only one bit.
*  Two most-often-used values are shortened.
*  Only the used range is considered.
*  Zero is excluded if not used.
*  In a different value, the original value is skipped.

Any ideas to shorten this further?
