I need a math genius to explain how many Chess positions there are.

1x64=24+4+36 36x55+4x60+24x58=3612

3612 is the number of positions possible with just 2 kings

3612x62x61=13660584

13660584 is the number of positions with 2 queens and 2 kings

this was the best my online calculator could handle so this is my solution to the number of positions in chess

The upper bound that I can calculate is 5.58×10⁵² positions.

The number of both king positions on the board is (4×60)+(24×58)+(36×55) = 3,612.

The number of ways to place 15 white pieces into the remaining 62 squares is less than C(62, 15)×6¹⁵.

The number of ways to place 15 black pieces into the remaining 47 squares is less than C(47, 15)×6¹⁵.

So we have upper bound 3,612 × (C(62, 15)×6¹⁵) × (C(47, 15)×6¹⁵) or about 5.58×10⁵² positions. This number includes pawn promotions and many illegal positions.

I read this, but it includes only legal positions:

Possible Positions: 10^43 to 10^50

Also this:

Possible games (move sequences): around 10^120
