title: 'Problem 341: Golomb''s self-describing sequence'
|
|
---
|
|
|
|
## Description
|
|
<section id='description'>
|
|
The Golomb's self-describing sequence {G(n)} is the only nondecreasing sequence of natural numbers such that n appears exactly G(n) times in the sequence. The values of G(n) for the first few n are
|
|
|
|
|
|
n123456789101112131415…G(n)122334445556666…
|
|
|
|
You are given that G(103) = 86, G(106) = 6137.
|
|
You are also given that ΣG(n3) = 153506976 for 1 ≤ n < 103.
|
|
|
|
Find ΣG(n3) for 1 ≤ n < 106.
