Dyadic transpose has been famously inscrutable since the days of APL\360.
Just the other day Jeanne and I were invited to Charles Brenner's home in Oakland, and I am reminded that he was the author of the first dyadic transpose. First he wrote a high-level APL model, next an assembly-language level APL model, and finally the 360 assembly language version. Somewhere I have a printout of these.
I have Erdos number 2, and Charles is the only other Erdos 2 holder that I know.
Charles is a Stanford graduate, as are Larry Breed and Roger Moore. He spent some years in England, supporting himself by playing in bridge games for money. We were both in the Iverson group at IBM Research. He visited Jeanne and me in Media, Pennsylvania when I worked in the APL group there (1971-74). He played his violin when he visited us.
