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.

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)
