geometry - Calculate center coordinates of circles surrounding a larger circle

I want to draw, say, 8 smaller circles that are adjacent to the big circle the edge of a big circle, similar to this picture.
enter image description here



I know the center coordinates of the bigger circle (A,B), its radius (R),radius of the smaller circles (r), and the number of circles I want to draw (n).




My question is very similar to the one discussed there, with one exception. I want a formula that calculates center coordinates of circles adjacent, not those on the edge of a bigger circle.
Mathematics is not my strongest side (to say the least), so I'd greatly appreciate any help. Thank you!
