    92 The seek elements allow to jump back or forward. The block size can be used to seek 1 block forward.[[BR]]
    93 Allow to seek back and forward in O(ln(n)) time without a seeking table. Have to find something like [http://www.cipr.rpi.edu/~pearlman/papers/EI05_fastaccess_ycp.pdf this paper][[BR]]
