Consejo, hazlo en orden: empieza desde el 1 y sigue -->

1, 2, 3, 4, 5

1, 2, 4, 3, 5

1, 2, 5, 4, 3

1, 2, 3, 5, 4

Ahí tienes 4 formas y no hay mas combinaciones si dices que son 20, porque 4 formas de 5 numeros 20.

Luego empiezas con el 2:

2, 1, 3, 4, 5

2, 3, 1, 4 ,5

2, 3, 5, 4, 1

2, 3, 4, 1, 5

y creo que es así ahora sigue tu que me cansé xD
