BACK to PROCEDURE All 2-multiples sieved out (missing below). Then child's bottle-caps show 3 not a Table-Number, but Row-Number.
* * | * * * | WE NEED ONLY TEST FOR ROWS OF THE GNOMON,
*   |      ROW-NUMBER 2, JUST DISCOVERED. BUT WE CAN'T
BUILD 3 AS A TABLE OF 2's.
So we can only form TABLES from ROW-NUMBER (GNOMON) 3. Then, each 3-multiple is a TABLE-NUMBER, to be SIEVED OUT! Note!! The FIRST MULTIPLE of 3 is ITS SQUARE: 3 X 3
