The number of arrangements that a group of 6 can be formed depends on what you mean by "arrangements".
If you mean the number of ways you can order the 6 elements in a linear sequence, it would be calculated as 6 factorial (6!) which is equal to 6 x 5 x 4 x 3 x 2 x 1 = 720.
If you mean the number of subsets that can be formed from the 6 elements (including the empty set and the set with all 6 elements), it would be 2^6 which is equal to 64.
Please clarify your question if you meant something different.
