Try this option:

there are two ways to resolve this task:

1. the 1st in this sequence is for 6 bands, the 2d in this sequence is for 5 rest bands, the 3d in this sequence is for 4 rest bands, the 4th in this sequence is for rest 3 bands, the 5th in this sequence is for rest 2 bands and the 6th in this sequence is for the last 1 band. Using the logical rule 'AND': A=6*5*4*3*2*1=720.

2. According to arrangement rules it is the formula: A=n!, where n - number of bands.

A=6!=720.

answer: 720.
