When the Chess pieces on Bobby Fischer's “Random Chess” are randomized, how many different positions can be legally yielded?

I know the King is placed somewhere between the two Rooks, and the Bishops should be placed on opposite colors as the traditional Chess.

Thank you,

Dear viewer,

There are 960 legal possible positions in the Fischer's random Chess.

The following javascript will let you generate and view all 960 possible variants with their respective FEN strings:
