As an hommage to @eyl327's "can you name the country code?" puzzles. Here is one more:
Given the country codes of the 10 countries in the following table, can you figure out the country code of Germany?
Bhutan TGH Gabon AFE Zimbabwe WIG Uruguay YHJ Malta TFF Finland IHF Hungary UHG United Kingdom KNE Republic of the Congo GSE Algeria ZHB Germany ...
the real country-code is not used
the country's full name is not used directly and no single letters are taken from it.
One derives from a number, one from a count and one is already a character. The order might be different.
An earlier version of the puzzle had DSE instead of GSE as the code for the Republic of Congo. This mistake was correctly pointed out by @eyl327 and was the result of a geopolitical mixup.
