Okay, so SP numbers their rows from the top down, as in 1-1-2-3-4-4. That is the typical arrangement on a keyboard. They make a tall Row 5 profile, but it is rarely used.
So, for a full 104 set, what you will receive is the following:
Row 1: 36pc 1x1, 1pc 1x2
Row 2: 18pc 1x1, 2pc 1x1.5, 1pc 1x2 vertical
Row 3: 11pc 1x1, 2pc 1x1 with homing bar, 1pc 1x1 with homing bump, 1pc 1x2 vertical, 1pc 1x1.75, 1pc 1x2.25
Row 4: 18pc 1x1, 1pc 1x2.25, 1pc 1x2.75, 7pc 1x1.25, 1pc 1x2, 1pc 1x6.25
