Bimagic cube — In mathematics, a bimagic cube is a magic cube that also remains magic if all of the numbers it contains are squared. In 1934, Cazalas attempted but failed to construct a bimagic cube. David M. Collison apparently constructed a bimagic cube of… … Wikipedia
Multimagic cube — In mathematics, a P multimagic cube is a magic cube that remains magic even if all its numbers are replaced by their k th power for 1 ≤ k ≤ P. Thus, a magic cube is bimagic when it is 2 multimagic, and trimagic when it is 3 multimagic, tetramagic … Wikipedia

Prime number — Prime redirects here. For other uses, see Prime (disambiguation). A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is… … Wikipedia
Colossally abundant number — In mathematics, a colossally abundant number (sometimes abbreviated as CA) is a natural number that, in some rigorous sense, has a lot of divisors. Formally, a number n is colossally abundant if and only if there is an ε > 0 such… … Wikipedia
Composite number — A composite number is a positive integer which has a positive divisor other than one or itself. In other words a composite number is any positive integer greater than one that is not a prime number. So, if n > 0 is an integer and… … Wikipedia
