Octants are the grid elements of PABLO. In the logical domain octants are, in 3-dimensional case, cubes with size function of their level. Each octant has 8 nodes, 12 edge and 6 faces ordered with Z-order as shown below.

The main feature of each octant are:

• x,y,z : coordinates of the node 0 of the octant;
• Morton index : classical Morton index defined anly by the coordinates (info about level used additionally for equality operator);
• marker : refinement marker can assume negative, positive or zero values, wich mean a coarsening, refinement and none adaptation respectively;
• level : octant level in the octree, zero for the first upper level.
• balance : flag to fix if the octant has to 2:1 balanced with respect to its face neighbours.
