88 is: . a refactorable number. [1]a primitive semiperfect number. [2]an untouchable number. [3]a hexadecagonal number. [4]an Erdős–Woods number, since it is possible to find sequences of 88 consecutive integers such that each inner member shares a factor with either the first or the last member.
Fuller does not give a formal definition for this term, but from the examples he gives, it can be understood to be those numbers that contain a factor of the primorial n#, where n≥13 and is the largest prime factor in the number. Fuller called these numbers Scheherazade numbers because they must have a factor of 1001.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
What does 888 mean? Here's a dive into the meaning of the angel number 888 or 8888 according to psychics and numerologists. Angel Number 888: Why seeing this number could mean abundance is on the way
3. Between two groups, may mean that the first one is a proper subgroup of the second one. > (greater-than sign) 1. Strict inequality between two numbers; means and is read as "greater than". 2. Commonly used for denoting any strict order. 3. Between two groups, may mean that the second one is a proper subgroup of the first one. ≤ 1.
888 is a practical number, meaning that every positive integer up to 888 itself may be represented as a sum of distinct divisors of 888. [2] 888 is equal to the sum of the first two Giuga numbers: 30 + 858 = 888. [3] There are exactly: 888 trees with four unlabeled and three labeled nodes, [4] 888 seven-node undirected graphs without isolated ...
This can also apply to limits: see Vanish at infinity. weak, weaker The converse of strong. well-defined Accurately and precisely described or specified. For example, sometimes a definition relies on a choice of some object; the result of the definition must then be independent of this choice.
Random variables are usually written in upper case Roman letters, such as or and so on. Random variables, in this context, usually refer to something in words, such as "the height of a subject" for a continuous variable, or "the number of cars in the school car park" for a discrete variable, or "the colour of the next bicycle" for a categorical variable.
