delete lines between patterns

Hi, I've searched in this forum all day long but was not able to find enough codes to help me do a task. The only code that I can come up with is this:

sed '/[0-9] [0-9] /,/[0-9] [0-9] /{//p;d;}' inputfile > outputfile

I would like to sed/awk/grep a file for two patterns and then delete the lines between those patterns. Please see the inputfile below. This is just a small portion of a lengthy file. Everything in bold should be deleted.

In this case, I would like to search for the first pattern [0 0 2] and the last pattern [2433 2433 2], then delete every line between these patterns but keeping the line [ANT_2] above the line [2433 2433 2]. Similarly, I would like to search for the first pattern [0 0 4] and the last pattern [1 1 2], then delete every line between these patterns but keeping the line [ANT_6] above the line [1 1 2]. The number of lines between these pattens can vary. The only thing that I can see that is constant is the [0 0 ].

Any help or suggestion would be greatly appreciated.

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
