in how many ways can 8 different types of flowers be strung

8 different flowers strung into a garland can be arranged in (8-1)! / 2 = 2520 ways.

Why a Garland is Circular

Garlands form a circle where rotations look identical, so we fix one position and arrange the remaining 7 flowers linearly: 7! = 5040 arrangements.

Since clockwise and anticlockwise directions are the same for a necklace-like garland, divide by 2: 5040 / 2 = 2520 total distinct ways.

This standard permutation formula applies to 8 distinct items without extra constraints like "particular flowers together."

Step-by-Step Calculation

  1. Total linear arrangements of 8 flowers: 8!=403208!=403208!=40320.
  2. For circular arrangement (fix one flower): (8−1)!=7!=5040(8-1)!=7!=5040(8−1)!=7!=5040.
  1. Account for rotational symmetry and flip symmetry: divide by 2, yielding 7!2=2520\frac{7!}{2}=252027!​=2520.

Common Variations

Many online discussions add conditions (e.g., 4 flowers always together), leading to answers like 288 or 4!×4!/24!\times 4!/24!×4!/2.

  • No constraints : 2520 ways, as above.
  • 4 together : Treat as one unit (5 units circular: (5−1)!×4!/2=288(5-1)!\times 4!/2=288(5−1)!×4!/2=288).

Without specified constraints, the basic circular garland gives 2520.

TL;DR: For 8 distinct flowers in a symmetric garland, it's 7!2=2520\frac{7!}{2}=252027!​=2520 ways.
