• total huruf = 3
• huruf ganda = (-)

Banyak susunan:

P = 3!

P = 3 × 2 × 1

P = 6 susunan.

N = 3

U = 2

G = 2

I = 1

• total huruf = 8
• huruf ganda = N(3), U(2), G(2)

Banyak susunan:

P = Total huruf! / huruf ganda!

P = 8! / 3! × 2! × 2!

P = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (3 × 2 × 1 × 2 × 1 × 2 × 1)

P = 40.320 / 24

P = 1.680 susunan.
