How many permutations can we have of:

12 distinct items arranged around a circle?

Circular Permutation:

Take n distinct permutations

Arrange them around a circle

Circular Permutation Formula

P_n = (n - 1)!

Plug in n = 12

P₁₂ = (n - 1)!

P₁₂ = (12 - 1)!

P₁₂ = 11!

P₁₂ = 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
