is there an IC that allows one to take in N inputs and permute them to N outputs based on other inputs?

"Permutate" them? Yes.  Here on Earth, we call it a
"microcontroller".  Or, possibly, a "ROM".

(I guess if there are N inputs then there are N! permutations and one would need log[2](N!) control lines?) (and I'm not talking about in software though. I might need upwards of 40 inputs or more (though maybe one could cascade smaller ones to make larger ones?)

i.e., I just want to have a "controlled" permutation of N lines. Maybe control the lines using a serial interface instead of having all those control lines.

The transition from the parallel to the serial path is appropriate
if you can spare the time...

Could it be a crosspoint IC like they used in telephone
installations??
