Solved and Unsolved Problems From The On-Line Encyclopedia of Integer Sequences
Speaker: Neil J. A. Sloane, Mathematics Department, Rutgers University, Piscataway, NJ.
Abstract: The On-Line Encyclopedia of Integer Sequences is a database of number sequences, which in its fiftieth year now contains nearly a quarter of a million entries. This talk will describe some of the highlights, including the toothpick sequence, curling numbers, ``lunar'' arithmetic, and some very unusual recurrences. There will be several unsolved problems, music, and a movie.
