How to control the whole board with 8 standard pieces (one king, one queen, two rooks, two knights, two bishops)?

P.S. A piece doesn't control a cell simply by staying on it, so another piece must control it.

It's a studied problem: Oxford journal page

The three possible solutions are listed at the top of page 4.

Three different chess diagrams where the 8 officers cover the whole board

Also noteworthy: there has been no option found with the bishops on opposing colors.
