Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

A115839 Self-describing sequence. The n-th integer of the sequence indicates how many integers of the sequence are strictly < 5n. 0

COMMENTS

Terms computed by Gilles Sadowski. In building step by step the sequence one has sometimes the choice for an integer. If so take the smallest available one.

LINKS

Table of n, a(n) for n=1..63.

EXAMPLE

A(7)=15 because there are 15 integers in the sequence which are strictly < 35 (they are 1,5,6,7,8,10,15,20,25,26,30,31,32,33,34)

CROSSREFS
