HArd problem

In how many ways can we seat 3 pairs of siblings in a row of 7 chairs,

so that nobody sits next to his or her sibling? (One chair will be left empty, of course.)

1.

Suppose we have six persons

a₁,a₂,b₁,b₂,c₁,c₂

and i assume that a₁a₂... and a₂a₁... are distinct combinations!

then:

Let one pair Number 1 and Number 2

Let one pair Number 3 and Number 4

Let one pair Number 5 and Number 6

Let one empty chair Number 0

so the final answer is 1968 ways can we seat 3 pairs of siblings in a row of 7 chairs, so that nobody sits next to his or her sibling

2.

Suppose we have six persons

a₁,a₂,b₁,b₂,c₁,c₂

and i assume that a₁a₂... and a₂a₁... are not distinct combinations!

then:

Let one pair Number 1 and Number 1

Let one pair Number 2 and Number 2

Let one pair Number 3 and Number 3

Let one empty chair Number 0
