## Description
|
||
|
|
<section id='description'>
|
||
|
|
La secuencia autodescriptiva de Golomb {G (n)} es la única secuencia no decreciente de números naturales, por lo que n aparece exactamente G (n) veces en la secuencia. Los valores de G (n) para los primeros n son
|
||
|
|
|
||
|
|
|
||
|
|
n123456789101112131415… G (n) 122334445556666…
|
||
|
|
|
||
|
|
Se le da que G (103) = 86, G (106) = 6137.
|
||
|
|
También se le da eso ΣG (n3) = 153506976 para 1 ≤ n <103.
|
||
|
|
|
||
|
|
Encuentre ΣG (n3) para 1 ≤ n <106.
