Hola Snark.
Se trata de encontrar tres números de tres cifras de modo que el 2º nº sea
el doble del 1º y el 3º el triple del 1º y además los nueve dígitos
utilizados deben ser todos distintos.

Me sorprendió que hay unas cuantas soluciones.
Se agradecerán ideas algebraico-matemáticas para acotar el problema (para
evitar la solución a base de probar o programándolo).

Un saludo,
Emilio Martín
