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.
