Factorial and Permutation Calculators

Calculator	Formula	Description
Factorial Calculator	n!	Calculates the product of all positive integers up to n.
Multifactorial Calculator	n!, n!!, n!!!, n!!!!, n!!!!!	Computes higher-order factorials (double, triple, etc.).
Even Permutations Calculator	n! / 2	Finds the number of even permutations in a set.
Odd Permutations Calculator	n! / 2 (for n ≥ 2)	Calculates the number of odd permutations for sets with n ≥ 2.
Circular Permutation Calculator	Pₙ = (n – 1)!	Determines circular arrangements where order matters in a loop.

Sample Selection Calculators

There are four fundamental ways to select a sample of r elements from a set of n objects, depending on whether order matters and whether replacements are allowed.

Calculator	Formula	Order Matters?	Replacements Allowed?
Combinations Calculator	nCr = C(n, r) = n! / (r! × (n – r)!)	No	No
Permutations Calculator	nPr = P(n, r) = n! / (n – r)!	Yes	No
Combinations with Replacement Calculator	CR(n, r) = C(n + r – 1, r)	No	Yes
Permutations with Replacement Calculator	PR(n, r) = nʳ	Yes	Yes

Each calculator simplifies complex mathematical operations into easy-to-use tools for quick and accurate results — ideal for combinatorics, statistics, and discrete probability studies.
