These are basic concepts in combinatorics, which is the branch of mathematics that deals with counting, arrangement, and selection of objects.
Permutation
Permutation is the arrangement of any object in any particular order. In the case of a permutation problem, the permutation order is important. To this end, different permutation orders will yield different permutations.
Combination
This is referred to as a combination whereby the order is immaterial. In combinations, what matters is not how the elements chosen are arranged but which ones are chosen.

Determine whether Order Counts: For permutations, order counts; for combinations, it does not.
Use Factorials Carefully: Use Factorials Wisely Factorials increase rapidly. Reduce wherever possible and pay attention to the size of numbers.
Break Down Complex Problems: Break up complicated problems. For problems with constraints, break them up into workable cases and add in the solutions.
Practice Circular and Group Selections: These problems are common in the exams, so one needs to be conversant with circular permutations and selections with restrictions.
Focus on Time Management: Train regularly in increasing speed and error reduction.
A permutation is an arrangement of items in a specific order. In permutations, the order of items matters.
A combination is a selection of items where the order does not matter. In combinations, the arrangement is irrelevant; only the selection of items counts.
