For future reference, here are the standard nomenclatures for different sequence patterns:
Generally, i is the initial value, j represents the number of steps, and n is the step value. Using a # changes the value to a count.
0..10..3 = A sequence of 0 to 10 by 3.
0..10..#3 = A sequence of 0 to 10, counting 3 times.
0..#10..3 = A sequence starting at 0, counting 10 times by 3.
