Power ABC

Alphabet. Alphabet Power
By the alphabet, we will mean a set of letters, punctuation marks, numbers, brackets, and other symbols used in the text. The alphabet should also include a space, i.e. a gap between words.
The total number of characters in the alphabet is commonly referred to as the alphabet power. We will denote this value by the letter N. For example, the power of the alphabet of Russian letters and the marked additional characters is 54: 33 letters + 10 digits + 11 punctuation marks, brackets, space.
I'm wondering what's with the eleven punctuation marks? And to create a minimal font, you need to add at least 33 uppercase characters, not to mention the double keyboard with the Latin alphabet - it more than fits 256 characters or two to the eighth power. But this is all without considering the meaning... Zero... What does the article say?
A text consisting of a meaningless combination of characters will have a non-zero information volume.
Uh... zero information volume with an idle power of 54-87.
Uh... Hardly found punctuation marks!
As you know, there are 10 punctuation marks in the modern Russian punctuation system: period [.], comma [,], semicolon [;], ellipsis [...], colon [:], question mark [?], exclamation mark [!], dash [-], parentheses [()] and quotation marks [" "].
Blah, blah, blah...
as always, the 11th main punctuation mark is missing in the answers - a space.
total. The minimum number of characters is 87. The formula 54:33 is suitable, but we will supplement it and list all the symbols in rows.
87=(33:zz)+10+11
