Knuth Releases Another Part of Volume 4

junge_m writes "Donald Knuth has released another of his by now famous pre-fascicles to Volume 4 of his epic: Pre-fascicle 2c is all about 'Generating all Combinations' supplementing his pre-fascicles 2a and 2b. Furthermore he challenges us all to do more of his daunting exercises and report our success. He thinks we are way too lazy in this respect! So come on slashdot crowd: Do your homework and get the credit from the grandmaster himself!"
