Kurzesagt in a Nutshell said that the number of possible protein combinations the human body can have is 6.8 x 10^495. I wanted to multiply it by 20 million (which is the hypothetical number of possible alien civilizations in the Milky Way galaxy give or take). What is the answer and what is the name of that ridiculous number? I looked online and see many different names for super high numbers like quattordecillion and centquinsexatillion to name a few.
