Antti Karttunen, Table of n, a(n) for n = 1..10082

EXAMPLE

Viewed as an irregular table, the sequence is constructed as:

"Row"

[1] 1; (by convention, a(1)=1)

[2] 1; (because A061395(2)=1 (the index of the largest prime factor), we have here terms from 1 to 1)

[3] 1, 2; (because A061395(3)=2, we have terms from 1 to 2)

[4] 1;

[5] 1, 2, 3; (because A061395(5)=3, we have terms from 1 to 3)

[6] 1, 2; (because A061395(6)=2, we have terms from 1 to 2)

[7] 1, 2, 3, 4; (because A061395(7)=4, we have terms from 1 to 4)

etc.
