I'm not sure if you are after current sectors or not as those maps are now incorrect. I'm not sure 30, 31 or 33 ever existed, S32 & 34 are above S27 & 28, S24 is actually now S01 north (divide line approx PEPIS to OCK) and the S24 on the map is actually S5, S35 and S36 are the high level Westend sectors, S22 is a Channel sector, S19 was split in two. So basically West is 7 sectors, North is 7 sectors, East is 6 sectors, Central is 5 sectors and Channel is 8 sectors, although S21 cannot be ever split out on it's own anymore, it has to be with either S20 or S22.
