 OFFSET 1,1 COMMENTS The sequence in binary begins: 2 1000 3 1100 5 1010100 7 1011100 The final 0 bit represents an exponent of 1. Because this is a prefix code, there is a one-to-one mapping between the integers and integers representing their factors, provided that the coded factors and exponents are adequately delimited, such as by inserting additional 0 bits. For example, 75600 = 2^4 * 3^3 * 5^2 * 7 is representable as 100^101000 110^110 101010^100 101110^0 -> 1001010000110110010101010001011100 = 9946354780 decimal. This representation is unambiguous because, e.g., the incorrect reading 1001010000110 splits as 100101000 0110 or 100^101000 0^110 -> 2^4 * 1^3, which is clearly wrong.
