Large integer bell numbers this application calculates the bell numbers using a large integer package of the author's design and implementation the bell numbers are the total number of partitions of n-element set this program calculates the bell numbers using the well known recurrence relationship.
With the stirling matrix and the pascal matrix , we show that () satisfies a type of generalized stirling recurrence then, by expressing the sum of components of each row of as -bell number, we investigate properties of -bell numbers as well as -peirce matrix. In number theory and enumerative combinatorics, the ordered bell numbers or fubini numbers count the number of weak orderings on a set of n elements (orderings of the elements into a sequence allowing ties, such as might arise as the outcome of a horse race.
