There are 105 voters. So a "majority"
requires at least 53 voters.

I have listed all solid coalitions.
And there is no solid coalition with
at least 53 voters.

So mutual majority says nothing.

There are only 31 voters who strictly prefer
candidate A to every other candidate. And
there are only 51 voters who strictly prefer
every candidate in {A,B} to every candidate
outside {A,B}.
