- Different territories are represented by different colours and letters; separated parts of the same territory are represented by the same colour and letter, with a different number added to each smaller part of that territory .
* A:
** possesses 5 exclaves : it is impossible to go from the main part of A to any of these parts going only through territory of A; however:
*** A1 and A2 are not enclaves: neither of them is surrounded by a single "foreign" territory;
*** A1 is a semi-enclave and a semi-exclave: it has an unsurrounded sea border;
*** A2 is an exclave of A: it is separated from A;
*** A3 is an enclave: it is totally surrounded by B;
*** A4 and A5 are counter-enclaves : territories belonging to A that are encroached inside the enclave E;
** contains 1 enclave : "foreign" territory totally surrounded by territory of A;
** contains 1 counter-counter-enclave, or third-order enclave .
* B:
** contains 2 enclaves .
* C:
** continuous territory, contains no enclave or exclave
* D:
** is an enclaved territory: it is territorially continuous, but its territory is totally surrounded by a single "foreign" territory .
* E:
** is an enclaved territory: it is inside A;
** contains 2 enclaves , which are counter-enclaves of A;
** possesses 1 counter-enclave , which is a counter-counter-enclave as viewed by A and contained within A5.
In topological terms, A and E are each unconnected surfaces, and B, C and D are connected surfaces. However, C and D are also simply connected surfaces, while B is not . (en)
