What are the Komi grammatical cases?

I have read on Wikipedia that the Komi language has 27 grammatical cases. I would like to know which are they.What are the Komi grammatical cases?
So far I have found 16 cases: nominative, genitive, possessive, allative, accusative, instrumental, comitative, abessive, consecutive, inessive, elative, illative, approximative, egressive, prolative, terminative. The number of morphological forms of cased nouns is doubled by two different possessive suffix classes: individual possession suffixes and collective possession suffixes. Hope, it helps. If I come across more cases in the Komi language, I'll let you know (I am reading the Komi grammar right now)
