First 11 values of A121387 coincide with apparently unrelated new seq

[Ralf Stephan]

Thanks Al for your explanation of the 1st row of the table:

> Table A121388 is based on parity and the number of factors as  illustrated:
>  
>        1 1     3 3     5 5     9 3 3    15 3 5    25 5 5    27 3 3 3   45 3 3 
> 5   75 3 5 5   125 5 5 5   81 3 3 3 3  135 3 3 3 5  225 3 3 5 5  375 3 5 5 5  
> 625 5 5 5 5

but I'm too stupid to see how you would construct e.g. the 2nd row:

7 	13 	21 	35 	65 	63 	105 	

Can you help again, please?
