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.

Table of n, a(n) for n=1..66.

Example

A(7)=12 because there are 12 integers in the sequence which are strictly < 49 (they are 1,7,8,9,10,11,12,14,21,28,35,42)
