It's probably not very fast, but here's a very short RPL program (48G/GX or later) that returns the Nth row of Pascal's triangle:

Code:

<< IDN ->DIAG NEG PCOEF >>

BYTES: 26.0 #2587h

EDIT: Here's an even smaller one that's a tad faster:

Code:

<< 1. ->LIST -1. CON PCOEF >>

BYTES: 25.5 #E698h

<0|ɸ|0>
