Some facts#
- Variation consists in choosing any number of elements from the pool and then building a new sequence from them.
- Sequence length after variation can be different than a source sequence. Depending on whether the element can be used again or not, it can be longer, shorter or the same as the length of the original one.
- If the number of elements in the pool is n, and we choose k elements, the number of possible variations is:
or if we assume that the same element (e.g. the letter of the alphabet) we can use more than once:
- Variation with repetition is also called n-tuples.
- Variation without repetition is also called k-permutation of n.
- ⓘ Hint: More combinatorial items on Calculla:
- combinatorial tables - short crib with common combinatorics related formulas,
- permutations generator - simple tool to create list of all possible permutations (with or without repetition) based on given input pool of items,
- combinations generator - simple tool to create list of all possible combinations (with or without repetition) based on given input pool of items,
- variations generator - simple tool to create list of all possible variations (with or without repetition) based on given input pool of items.
