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

 OFFSET 1,2 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 Sequence in context: A202014 A319266 A263093 * A200259 A339746 A262513 Adjacent sequences: A115836 A115837 A115838 * A115840 A115841 A115842 KEYWORD base,easy,nonn AUTHOR Eric Angelini, Feb 01 2006 STATUS approved
